as far as the cheapest models would be a deluxe tinker than a swisschamp
You do need to put back the bushings and let the pins stick out 1mm above them.Not as you described: cut off 1mm and then place back the bushings
So... I tried to file the corkscrew and put in on the back of the openers. It worked more o r less. I guess I should have modified also the spring a bit, but already sanding 0,5mm off the corkscrew was a pain in the butt. The most annoying thing were the scales. While taking them off almost all the bushing-slots broke because of the bushing “tooth” (I never noticed that on nowadays knives, I am missing something?) so they are not nice and close to the liners anymore. I also did some experimenting so probably the whole thing is not really straight. But it works fine, the three tool are snapping as before. Thank you everyone for your help (Image removed from quote.)
Looks great! It's good you started with a small number of tools. You can learn from awl the process, correcting any mistake you might have made for the future.
Oooh great first(?) mod. How did the peening go? and how did you file the corkscrew?I dunno if you'd be interested, but a while back I made a topic about fitting the can and bottle opener in the blade layer in place of the blades:https://forum.multitool.org/index.php/topic,73874I should have remembered it sooner.
