The spring for the scissors on my Leatherman Style PS broke so many times that I made my own. I have already attached and fitted it to my own Style PS once. It can also be used for the scissor spring of the Squirt PS4, but some Squirts are riveted, and if you remove that pin, the pin can no longer be used, making the replacement difficulty higher. This is the price for the scissor spring only. The following is supplementary information. Please replace it at your own risk. Make sure the longer pin is on the side where the scissors move. Although you won't use the original scissor spring, we recommend keeping it for storage. ❗️Tools: Two Torx (6) drivers are required❗️ If possible, it would be easier if you have locking pliers, clamps, a vise, etc. If you have experience with disassembly and replacement, it should not be a problem. After production, I attach it to my own Style PS and conduct operational tests for at least 3 days to ensure there are no damages before listing. Finally, please do not use the reverse locking method as shown in the 4th photo. We recommend the standard locking method as shown in the 3rd photo. I have included installation diagrams to make it easier to understand how to attach it, with a relatively easy replacement method.
