The basic starter kit for carving and tooling leather.

This starter set comprising of camouflage, pear shader, beveler, veiner, seeder and background stamps gives the basics needed to start creating designs but cast from a less expensive metal.
A good place to start is with the Sheridan style flower in the Leather craft Handbook 6009-00. If you need a swivel knife there are several to choose from.
