Switchblade Parts and Automatic Knife Conversion Tools at KnifeKits.com


At KnifeKits, we offer an extensive line of automatic knife tools and replacement switchblade parts for DIY automatic knife making and repair. From coil springs for switchblade replacement to knife spring pocket cutting tools for automatic knife conversions, we have the automatic knife making tools and parts that you need. We also offer leaf spring material for repair and improvement of leaf spring fired switchblade knives. We even offer a line of DIY convertible button release knives that can be made into coil fired automatic knives for first responders, fire, rescue and other professions where one-handed automatic opening knives are needed and used daily.

We manufacture an extensive line of automatic coil springs which are designed to replace many popular coil springs in automatic switchblade knives today, from Combat Elite TAS Autos to Benchmade, Boker Top-Locks, Dalton Switchblades, S&W Automatics, Microtech Autos, Paragon Switchblades, Pro-Tech Automatic knives and other coil fired switchblade automatic knives.

We offer our replacement switchblade coil springs in heat-treated and cryo-treated form to insure maximum performance and long action life. These automatic knife coil springs are designed to be used in custom handmade automatic knife making, as well as high-performance automatic coil spring replacements for standard production switchblades and other automatic factory knives. In most cases, our automatic switchblade springs are far superior to replacement coils offered in standard switchblade designs and can increase the action quality of your knife with simple replacement. Other performance qualities offered in our replacement coils are torque control, with both high and medium torque spring designs available where applicable to benefit the knife action.

Since we manufacture our automatic switchblade replacement coil springs ourselves, we are not subject to the high pricing seen elsewhere and generally offer our replacement springs for less than any other switchblade replacement spring source available anywhere. Also, our automatic springs and other switchblade replacement accessories are designed by high-level custom automatic switchblade knife makers and are currently in use on many of the best automatic switchblade knives on the market today.
