Sewing needles and an awl are (possible) components in pocket kits and most SAKs and multitools will have a awl for scribing and punching. Heres a little alternative, horseshoe nails! They have a nice large head for gripping, softer temper ( you can hammer them into different configurations) and are asymmetrical ( to drive naturally away from living tissue.)They also cut easily with a multitool, something of a ordeal with better building nails. An additional trick while cutting or bending small hooks, nails or wire is to place the piece in an open clear ziplock bag. dropping or having a cut piece flying off is no fun.
