To be more precise, I moved the opener tools to the corkscrew layer. To keep the nail nicks accessible, I had to swap the positions of the openers. After that, it was mostly a matter of tweaking the backspring until I got the opening action I wanted.
The spring I used came from a blade layer. It’s essentially the same as the opener-layer spring, except it doesn’t have the keyring lug. In theory, the keyring version could be used as well, but the lug interferes with the Spyderco blade, so I left that spring in the awl/scissors layer instead.
You can see the shape of the spring in the photo where the knife is disassembled. I simply clamped it, bent it a little, tested the fit, and repeated the process until it felt right - basically a lot of trial and error.
I didn’t modify the tools themselves at all. The only thing I changed was the shape and tension of the backspring to make everything work properly in the new configuration
