Automatic Folding Knife Parts and Automatic Conversion Tools at

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

We manufacture an extensive line of automatic coil springs to replace many popular coil springs in automatic folders and pocket knives from Combat Elite TAS Autos to Benchmade, Boker Top-Locks, Dalton, S&W Automatics, Microtech Autos, Paragon Knives, Pro-Tech Automatics, and other coil fired folding knives. We offer our replacement coil springs in heat-treated and cryo-treated form to insure maximum performance and long action life. These automatic 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 folding knives and other automatic factory knives.

In most cases, our automatic coil springs are far superior to replacement coils offered in standard folding knife designs and can increase the action quality of a folding knife with simple replacement. Other performance qualities offered in our replacement coils are torque control, with Mega, Maxx, and High torque springs to improve the overall knife opening action. Since we manufacture our replacement coil springs, we are not subject to the high pricing seen elsewhere and generally offer our replacement springs for less than any other folding knife replacement coil spring source. Also, our automatic springs and other auto opening replacement accessories are designed by high-level custom automatic folder makers and are currently in use on many of the best automatics on the market.
