Comes with three springs that take around 15, 30, and 45 lb of force to compress the thumb pad flush with the handle. Over-tightening can slightly increase the resistance, and under-tightening can slightly decrease the resistance.\u003c\/p\u003e\n\u003ch3\u003eInterchangeable springs\u003c\/h3\u003e\n\u003cp\u003eChange springs by twisting to unscrew the inner plastic ring from the wood handle. The nut on the other end of the bolt opposite the thumb pad may loosen when unscrewing the inner plastic due to the direction of the threads. If the plastic ring becomes stuck, place in freezer to shrink the plastic. A 12 mm or adjustable wrench can be used to loosen for tighten components.
