Nathan's Knife Kit from CRKT
This working softwood model of a lockback folding pocket knife is a great craft project for adult mentors and children ages 7 and older. When assembled, the model operates exactly like a lockback folding knife, teaching the principles of levers, springs, and locks. All parts are shaped with safe rounded edges, and the project is ready to assemble without tools. Complete detailed instructions are included. Finished wooden knife is 4.75" long.
