After reading the "Spearing Deer" thread it got me thinking about the Illinois law of using prehistoric broadhead materials. It is legal to use materialssuch as flint, chert, or obsidian knapped arrows. The bow still must have a minimum pull of 40 lbs. Minimum arrow length is still 20 inches and the head must have a 7/8" cutting diameter.
Has anyone here every made their own arrows and knapped them with any of these materials to harvest deer. That is a goal of mine in the future. Any other stateallow the use of"prehistoric tips" on arrows.
