These little guys make handy little keychain tools. Sometimes it's nice to have a fine pointy tip for those little jobs like cleaning your fingernails or for cutting chores that require fine detail. These are 5/32" thick CPM 154 semi stainless cutlery steel and measure just over 2.5" long. The kydex sheath is set up for either keychain or neck carry and includes a length of bead chain.
