Jeff has a collection of knives and swords that he's quite fond of. His collection consists of: 3 butterfly knives, 4 butcher knives, 2 carving knives, 5 chef knives, 2 boot knives, 1 chris reeve combat fixed blade, 2 karambits, 2 scimitars, 2 katanas, 1 two handed claymore, 1 bokken (for practice of course) and 1 chokutō.

In his free time, he sharpens the knives and polishes the swords.
