Our 0.375 inch automatic coil springs are designed to replace many popular automatic switchblade knives from today's popular knife manufacturers. Some of these include Combat Elite TAS autos, Benchmade, Boker, Dalton, S&W, Microtech, Paragon, Pro-Tech and other frame coil fired switchblade knives. Our automatic coil springs are used by custom knife makers all over the world, where performance and reliability are a must.
Our High Torque springs will directly replace most existing springs. In many cases, you'll have more opening power than the current spring being replaced because of our consistency in manufacture and the additional heat and cryo treatment processes that we use. A strong, smooth opening action are the characteristic of this model.
