Another Bone Knife

Bone knives are excellent for tasks requiring a more sturdy edge than stone normally is. For example, while cutting true tinder fungus with a stone is a pain, shaving it off with bone is easy. Bone is also sharp enough for cutting non-fibrous vegetables, gutting fish and skinning small animals. In the latter task bone has the advantage of not normally being sharp enough to slice through the skin, especially if you have a rounded tip on the knife. Though I prefer to work with fresh bones I have been in short supply of bones for a long time since last hunting season so in this case I had to use an old sheep leg bone I found in a field.

Start by sawing halfway into the bone at the lower end margin of where the blade is supposed to be.

















Score around the sides and top so that the front piece is freed from the rest without cracking the rest of the piece. Score almost all the way through. Using water will help a lot.

















Split from the top and break off the waste. This waste piece was made into a small chisel. It might not be of very great utility, but I'll try it on green wood.

















Afterwards the blade was ground thinner and pointy. For cleaning fish I would ideally want a thinner tip, but I want a stronger edge on this one for broader application.

















I already had a birch bark sheath from a now broken knife to reuse.

Small and Simple Antler Comb

Start by scoring and breaking off a palm of antler. The antler in question here is reindeer/caribou antler. As usual, use hot water when working antler.














Score or scrape along the edges so you can split the piece with a wedge. My split wasn't totally successful, but I actually think the result got better because it ran off. It gave a stronger handle.














Start scoring the teeth.














The teeth should be rombic in cross section and of course have a little spacing in between. This you can achieve by scoring, splitting and abrading with a rough piece of quartzite between the teeth.














The handle was engraved with a stone flake. Take several turns, score first superficially, then deepen the grooves. The grooves can be highlighted with a mixture of charcoal and wax (best in my opinion) or charcoal and fat.

Aspen Bark Container Part 2

The container is sewn after it is dried. I drilled the holes with a flint tip. The rim was willow bark and so was the lashing. There are many possibilities of how to do this. If you use a good type of bark, which doesn't curl that much, you can butt the sides against eachother, but with aspen you pretty much have to overlap. This basket type is very sturdy and well worth the effort in making.

Wikkiup

My kids and I took off an afternoon to work on a wikkiup in a place that we have thought would be good to do it. We picked a spot right on a creek where there is a natural spring and we've been to the spot enough to know it doesn't flood at any time of the year.

Right near this spot are old broken cottonwoods which tend to break off in large splinters that leave huge slabs of material to use as shingles. There are also some green alders that were washed away at the bank and were blocking the creek somewhat. Alder, no matter if it's green or dry is very brittle and pretty large trunks can be broken off.

The point of this exercise is to show my kids that good dwellings can be made with what is available. When it's done is should be fairly rain proof and tall enough to have a fire inside. Right now it's drying a bit as it is very heavy from being green and the large slabs are still wet with the rain we've been having.





In the above picture you can see how we used the natural forks of the trees to make an interlocking center. You can make the center interlock very tightly by laying everything down on the ground first and interlocking it while it's on the ground. Then you raise it up in the middle and keep pushing it up. The increasing angle will really help bind the forks together.





The above shows the large slabs of cottonwood that will overlap as shingles.





This last pic shows the approximate size of the shelter. I can easily stand up and have room to reach up still in the center. It should sleep 4 pretty comfortably.

Aspen Bark Container Part 1

This type of container is to me the quickest way to make high quality containers there is. It has the limitation that it is to a great deal only usable in spring and summer. After the bark has been folded you have a ready made container. To make it more durable and useful however, it is an advantage to dry it before you do the final steps. Otherwise you will experience curling and shrinking of the bark, making the construction loose and without a great fit.














First choose a section of Aspen (or specie with bark of similar structure) which is fairly straight and knot free. Score around the tree in the top of the piece you want, and do the same in the bottom. Then score diagonal line connecting the other two. Make sure you score all the way into the wood. You will kill the tree anyway, so there is no reason to be careful.














I use my flat moose antler wedge to pry loose the bark.














Determine the middle of the sheet by using a folded line. I have no picture of the process, only the curled sheet.














Score a shape across the sheet, resembeling the cross-section of a convex lense. I did this on free hand this time, but to get a more regular and beautiful shape you could make a simple birch bark pattern.














Fold it over and pull it over a log stump, bind around and leave it to dry. This is to prevent it from curling inwards. Not very easily achieved primitively, so I am currently testing another method, which I have never seen demonstrated anywhere. If it works out well, it will be presented in a book.

Heat Treating Rocks

Norway is full of rocks, but very few of them have any particular value in knapping. Flint is only occationally found on the southern coast in small pebbles and rhylite in one location in the west. Quartzite is too hard, quartz breaks a little irregularly and lots of others are more or less useful.

I had heard that quartz responds to heat treating, so I decided to test high grade quartz, quartzite and something that resembles metabasalt. The flakes, no more than an inch thick, were buried a few centimetres below the surface. A small fire was made on top and maintained for between 1 and 2 hours.














I then brushed the coals aside and let the ground cool for a little while. My immediate reaction when digging up the flakes were that the pieces of quartz seemed more shiny and glossy. There was no visible difference on the quartzite and metabasalt.














When testing the pieces I found that the quartz knapped much easier. The flakes travelled easier and didn't step in the regular fashion. It also felt sharper. On the quartzite, which supposedly doesn't respond to heat treating I found a small positive change, although it may be just my bias. The metabasalt just became more brittle and crumbled under any flaking.

I didn't expect any change during such a short time of exposure to such relatively small temperatures. As the results were quite pleasing, I'm not sure much more would be recommended with the quartz, since it may become too brittle, but it may be worth experimenting with higher temperatures and/or longer time in the ground with quartzite.

Sewn Birch Bark Box

Birch bark is extremely versatile and resilient. Consequently it can be used for making a lot of different things. You need bark of a certain quality to make this type of box.

Take a long piece of bark and roll it up double. Sew it up with some type of cordage. For such high strain, static applications, split spruce root is ideal.














I had limited amounts of spruce root available this time, so for the rest I used strips of willow bark. The bottom of the box and the top of the lid is doubled with bark in two different directions for added strenght. Stitching across the grain is always important to do when using birch bark. Otherwise the bark will most likely split.

That's the basics of it all, an excellent box for storing all sorts of small items. There are many tips and tricks regarding fitting and similar that doesn't fit in here. A more in depth tutorial will be in the upcoming book(s).

Buckskin Leggings Tutorial

It has been a while since I made a pair of leggings. My last set was stolen out of my friends pickup truck during a trip. The bag held all my buckskin clothes and was the only thing taken. It's been long enough now that I smile when I think of what the person who took this bag must have thought when they got home and opened it up!

When making clothes of any kind with buckskin it is crucial that the skin needs to be washed first. I don't mean a trip through the washer (which you can do with buckskin!) but rather a dip in some water. When buckskin is worked soft in a frame, which I do, it tends to come out in a 2 dimensional shape. Deer are obviously not 2 dimensional so getting the skin wet and slightly working a little as it dries allows it to come back to a more normal shape. After giving the skin a dip I wring out the smokey water, catching it in a bucket to be used later for a braining. The smokey water helps keep the brains from going sour and also make it a little easier when softening the skin. The reason you want to soak the finished skin is because if you don't you might end up with one leg that wants to twist weird ways or a sleeve that is shorter than when you started.

One should also try to find matching skins when making clothing. That is to say that the skins should match in overall thickness as your first priority and optionally in coloring. To help with color matching smoke two skins of the same thickness together. The skins I use here were not smoked as a matching set and you can tell the difference if you look carefully.

I have found it much easier to use old clothing that you like the fit of and taking it apart rather than useing patterns or measurements. I went to the second hand store and picked up these old jeans for 2$. I simply cut out the crotch and then split them up the outer side seam. They are now my pattern. You can see in the pic where I have laid the "pattern" on the washed skin. You will note that the skin is not flat but has curves in it. This is normal. Buckskin is not like working with any other material. Your finished garments will never look like they came out of a factory.

I traced an outline of the pattern onto the flesh side of the skin. You can use some sort of straight edge to help make up for the ripples but again, it's never going to be perfectly straight. Be sure to keep track of which side of your skin will be the front part of your leggings and which part is the back. The side of the pattern where you can see the old pocket from the jeans is the front side. It will be that side that is eventually made into the fringe.





This pic shows the buckskin that has been cut away from the back side of the legging and also the crotch area. Before you cut into buckskin make sure you think about what your doing, then think about it again as you cant really fix a screw up too easily with buckskin. I made the cut about 1/2 inch away from the exact tracing line of the back part of the leggings. This is to allow for a little overlap in the seam of the sides of the leggings. Next I used an awl to poke holes on the line of the back side of the leggings, or the side that has been cut. Do not expand these holes by shoving the awl through the holes. Leave these holes small. All holes exposed to stress will become larger over time. This is why you want to leave the holes small. These holes are about 1/2 inch apart. You can space them wider or smaller to charge the appearance but much further apart and you run the risk of the seams becoming saggy over time. Much closer together and you run the risk of having the seems rip into each other.





This pic shows the seam on the outside of the skin. This is called a running stitch. In this case this would be called lacing as this skin is not really stitched as much as laced together. There are many variations of making seams. I like this one for it's simplicity. You can get really crazy and make seams that look like little x's or seams that look braided. Whatever seam style you decide to do you want to make sure that when you cut your lace that you take note of the different thicknesses of the skin. Thinner areas on the skin will stretch much more than than thicker areas. So when you cut your lace make the cut wider in thinner areas and a little narrower in thicker areas. Get your lace wet and pretstretch it. No need to let it dry before using it but you can. Note also how the same side (hair side of skin) is showing on the lace as well.





When I lace I lace from the bottom of the leg and work my way up. I leave about 8 inches of lace on the bottom just in case I need to make adjustments somewhere. When I finish off the end of a lace I tend to just weave it on the inside of the garment rather than tie it off and cut it. That way I have something to work with later if needed and I also know I have a little stash of lace on me in the event I need one and don't have one. I don't lace the the very top and will show what I like to do there next. Now we have the skin laced up the side. The big flap on the right can be left as is or made into fringe. To me half the fun of buckskin is the fringe and as you will see I love to get nuts with the fringe.





There are a number of ways to make the part that keeps the leggings on you. Some folks suggest a suspender type set up while I prefer a belt. To make the belt loop I lace the inside part of the flap that is left on the inside of the legging. I fold it over to create the loop and include this in with the lacing on the top and keep going all the way up, folding over the outer extra skin. That way I have a strong loop that does not want to stretch.





Making the fringe is pretty simple. Just cut strips of skin until they are as small as you would like them. I like to make some initial cuts all the way along the lateral flap just to make sure my fringe is as even as I can get it.





I like the look of twisted fringe which was practiced by some aboriginal American tribes. I wet the fringe and then stretch each individual part of the fringe and twist them tight, giving a nice pull on the end.




I really suggest wearing the whatever your making around a bit before you do a lot of trimming. Again, you can't correct mistakes too easily and buckskin takes a lot of work to get to the point where you're making clothes and don't want to waste all that work. After you've worn it a while you will see and feel where you want to make some different trimmings. I am going to leave the upper parts of these intact for a while before I do any trimming.

And there you have them, leggings.

I really prefer leggings to pants for several reasons. My favorite reason is that they are adaptable. When you get up in the morning you put your skirt/breech cloth on and then add your leggings. When it warms up you simply take off your leggings, no need for a wardrobe change. When it cools back off then your leggings come back on. Leggings also cut down on laundry especially when used with a skirt which I what I prefer to wear with leggings. This makes them go for longer stretches where they don't need to be washed than do pants. While buckskin is pretty breathable it can get hot and musty in a hurry. Leggings cut that right out. Leggings also allow for much greater flexibility and range of motion than do pants and you never get butt sag as buckskin pants tend to do over time.

Some may think this a little drafty of a system but I have never had any problems with it having lived year round in a skirt and leggings outdoors. Buckskin is so naturally warm that a little ventilation is nice and the extra ventilation helps keep one cleaner in my opinion.

In final analysis the most important part of leggings is that leggings are just damn sexy!

Toe Bone Fishing Hook

This winter I have made a number of antler and bone hooks made in several different ways. A method I tried fairly recently I would say is more than likely my new method for making a bone hook. Bone has two major advantages over antler as a hook. It gets sharper and isn't as affected by water (antler softens a lot after some time). The disadvantage is usually that bone isn't as flexible and has a strong tendency to break, especially where cut agains it's grain. The toe bone hook follows the grain all the way and can be left thinner, which faciliates easier bait attachment and possibly higher overall efficiency. With other words, this is yet to me, probably "the ideal" primitive fishing hook. I know that the barrel cactus have even more suitable hooks, but that plant is unfortunately not to be found here.

First you need a toe bone. Clean it up well.














Grind both sides until you expose the marrow in the middle, this will make into a natural, hollow rectangular(ish) piece of bone.














Clean up the inside.














Cut at what you judge to be the most suitable place and cut the shape of the hook.














Round the edges of the hook and make it sharp.

Carved Snow Googles

I've made a couple of pairs of these before, but this one is the first with stone tools only. I didn't take any photos during construction, so I hope that my explaination will suffice.

First you need to find a bent piece of wood, mountain birch being a good alternative. I chopped it down with my moose antler axe and when I got home I split it in half so that one piece has the split surface facing out of the curve, while the other has the face on the inside. Use the one with the split face on the inside.

Determine how it will sit on your face and use a flake to saw it to lenght and make the groove for your nose. Clean it up with a beaver tooth or a flake. Beaver teeth works better when hollowing out the nose room since the edge is stronger. Take your time, making such googles isn't done in a flash. Try to do as much work as possible while it's green.

Next, measure where your eyes will be and carve out the eyeroom with beaver teeth. After this is done, chances are the wood will dry out very quickly, so do as much as you can at once. The slit through should be as long as possible, to allow for the best possible sidevision. Carving the slit is easily achieved and can be done both from the inside and outside. For maximum light blocking, go as narrow as you can.

Drill one hole in each end for the string. I used a hand drill tipped with a very thin bone point. It will burn hole more than anything else, but it works. Drill from both sides and punch (carfully) through with a bone awl. Finish it up, attach a line and coat it with charcoal (not done in photo) on the inside of the eyes.

Evenk Berry Picker Update

Two years ago, I made a makeshift Evenk berry picker when out in a woods, inspired by an article on a Swedish site and later also by Ray Mears in a tv-series. I was surprised by it's efficiency, but the workmanship didn't hold up for long.

I have been thinking about making a new one for a long time, even gathered the bark and the spruce root, but it wasn't until there recently was announced a berry picker contest on bcuk that I got the neccesary kick in the behind.

What I have done yet is to gather the materials and to make the rim. This was done quite a while ago, this summer. The rim is of willow and could with advantage have been of another, more sturdy material, but in the very far north that is one of the few materials available. The willow is so weak in that after it had been split and thinned, I wrapped the opposite half on as a support. The bark is strong, taking away the strain on the back and the opposite half evened out the compression.

Compression fractures developed in one place, and that place was straightened with boiled water. To keep it firm until it dried, I bound down a bone piece with some rawhide.

Willow Basket

Willow is very fast growing tree. That makes the wood weak, but the strong bark keeps an integrity to it. Harvest the red shoots, they are usually the best ones. The shoots that are still red has a large pith, but the bark is strong, so that they can be folded without breaking.

Harvest in winter, when the sap is down, the shoots seems to be less brittle then and their water content is lower. But still, dry them before you use them, to avoid the baskets becoming loose. It is better to reconstitute them afterwards, before using them. That wasn't neccesary with these shoots though, as they were so strong. When harvesting, there is no need for tools, the easiest method is just to rip them off the trunk with your hands.














To start the weaving, overlap four willows like on the photo. But four will not do it. It has to be an uneven number, otherwise the weave will end on the same place and that will not make a basket.














When you feel the gaps between the spaces become unmanagable, add in an even number of new strands. If you add in an uneven number, the result will be even and will not work (Said differently: Not 5+5=10, but 5+4=9.). Cut off all of the ends on the inside, as that will be hard to do on the finished basket.














When you have the size of the bottom you want, bend up the strands and tie them together in the top to keep them like that. Start weawing upwards. It is messy in the start, but if you are careful to keep the weave tight it will become progressively easier as you move upwards.














Weave it as high as you want it. When the top has become stable on it's own, you can release it in the top, that will make further weaving easier. Splice on the outside, as trimming later on the inside will difficult.


















Cut off the tops at a good lenght. Make them pointy, that will make tucking them back into the weave easier. Tuck them back over into the neighbouring strand.














Finally, trim off all the ends and the basket is finished.

Fishing Gorge

Due to a heavy work load at school and in the home I have had very little opportunity to test much of my new equipment yet. So, when the workload hopefully eases sometimes this summer, I'll have opportunity to test the fishing equipment some more too.

Anyway, having heard about the efficiency of the throat gorge for several years, I have decided to give it a go. My experience with metal hooks is that smaller and thinner is better. This is where I believe most practitioners fail today. To large and too crude.

I used the thigh bone of a black grouse. First it was sawed off in one end, then halfway through on the other. As usual, water helps reduce the work involved.














Four slithers was made by scoring it along the length in four places.














The pieces are scraped pointy in the end and all that is left is to tie a thin thread to the middle. I don't think it will slip, even without a groove. The smallest one is less than 1,5 cm long. Hopefully small enough for the small fish I usually go after.

Skin Pouch Update

To make the pouch easier to tie off, I made a lining of roe deer buckskin. The skin is cut against a board. Keep in mind that it is easier to cut reliably in a pushing motion rather than pulling.














The sinew thread is single ply strands from reindeer backstrap sinew. It is twisted like this to keep it together. For longer, stronger threads I'd use two ply threads, but for this project that wasn't needed.














The small tear down in the bottom is sewn tight with an antler needle. For this I used a simple overhand stitch. For the rest I used running, double stitches.














On the top of the lining I sewed in a short braided cord of elm bark to tie off the opening of the pouch. The knot here is excellent for tying off the end of a seam.














The finished result: A tinder pouch.
