:-) When David was a Cub Scout, I volunteered to teach his den all about knives, including knife safety (required for them to earn the card that gave them permission to buy a Scout knife (basically a blue Swiss Army knife) and/or earn knife-related badges. I brought in ... a whole bagful. Talked about blade grinds, blade shapes, different steels, handle materials, what shapes are good for what use and why. They did pretty good.
