Benchmade uses "six-lobe" headed screws exclusively throughout the assembly of our knives. Occasionally you may want to adjust blade tension, remove the carry-clip or simply check for any loosened screws, so we offer this handy kit for those purposes. Keep your Benchmade knife in tune with this 12 piece folding tool kit plus sharpener. Carry case included. This kit is in a handy "folding" layout that makes it easy to work on your Benchmade knife.
