We manufacture the world's most extensive line of automatic coil springs for knife conversion and replacement. From Combat Elite TAS Autos to Benchmade, Boker Top-Locks, Dalton Knives, S&W Automatics, Microtech Autos, Paragon Knives, Pro-Tech Automatic knives and other coil fired autos, we carry the coil size and strength that you need to get your favorite auto back to top firing shape.

We offer our replacement automatic coil springs in heat-treated and cryo-treated formats to insure maximum performance and long action life. Our springs can also be used in custom handmade automatic knife making, as well as high-performance automatic coil spring replacements for standard production folders and other automatic factory knives. In the vast majority of cases, our auto springs are far superior to the standard coil springs offered in most folding knife designs. They can increase the action quality of a knife with a simple spring replacement. Another performance quality offered in our replacement coils is torque control, with Mega, Maxx, and High torque spring designs to benefit the customization and control of a knife's opening action.

Since we manufacture our own automatic replacement coil springs, we cut out the middleman. We offer replacement knife coil springs in standard U.S.A. sizes for less than any alternate source available. Our auto springs and other folding knife replacement accessories are designed by custom auto makers and are currently in use on many of the best automatic knives on the market today.
