Carbon steel blades in a beech handle with a maple shoot sheath.
I make these all awls to have all of the design features I consider important for buckskin work:
1. High quality high carbon tool steel that holds a good point but is soft enough not to snap under torque 2. Short handle and blade so that the fingers can still grasp the buckskin when the awl is in the palm of the hand 3. Narrow blade that tapers all the way from the tip to the handle so you can customize the size of the hole to your sewing needs 4. Large, smooth, round base to distribute the pressure and prevent bruising.
Full round handles distrubute the pressure more and are nice for larger hands, but are rolly. 3/4 round handles are nice for smaller hands or large hands, fit in tool bags easier and don't roll off of tables. Full round handles tend to the most popular, but my personal choice is the 3/4 round.
