Hori Hori knife! Very hippy friendly. It is a Japanese gardening knife that can be used to prune and dig. Package the knife with a pair of bamboo thongs and a book on Zen Gardens. They are not razor sharp, and are not intimidating to sheeple. It may be a good introduction to knives as tools. Then, next year....get him a Spyderco. Maybe if you just buy through REI he will deem it hip to have. Most likely, being a gift from his son, he will value it.
