Arrowheads

I have a ton of projects going on now. Among them a fish trap, which will hopefully be finished by the end of this week. But I'm also working on a construction site these days. There is some slack during the day, while waiting for supplies and stuff. That is an excellent opportunity to knap a little. The two to the left have been made at work last week. The two right ones are made from some kind of English flint. The left one from Knife River flint, most graciously given me by Eskimoboy on paleoplanet.
