Benchmade uses six lobe, torx-like headed screws exclusively throughout the assembly of our knives. This engineered screw style offers a more "controllable" means of achieving tightness. Occasionally you may want to adjust blade tension, remove the carry-clip or simply tighten any loosened screws, so now we offer the The Bluebox ™ for those purposes. The kit includes various bit sizes with a Bit holder/ extension; molded plastic case which doubles as the handle.
