Ok, I just bought an auction for 12, 4 layer SAKS...with one purpose in mind...finding a way to convert either the bottleopener/flathead or the can opener/philips into a "combo" tool to replace the small knife. The reason is quite simple: The Victorinox Company are smurfholes for not selling compact variations for all their tools. Not only that, they purposefully don't make the bantam in 91mm just to make it harder to mod. So f them, I'm going to make it work so that more people can get custom Vics with one fewer layers, for a lot less. and I'm going to make a whole bunch of detailed videos to make sure everyone knows how to do it...No excuses Victorinox! If anyone has ANY information to shorten my process please please share them. Cheers.
Main problem is that the bottle and can openers are thicker than the combo tool and small blade. So you would have to make them thinner first.Also, they have a right-hand bend, whilst the combo tool and small blade are straight. But if you can thin them down, this bend is no problem.
All the time and effort you're about to sink into this (and the cost of the donors) soon adds up... You (and anyone else who wants a version of the SAK with a combo tool) would be better off buying a Compact to pull apart. You'll get a better product cheaper and more quickly at the end of it.
Ok, I'll pitch in with a couple of modding ideas for the cap lifter. I saw on a YT video that someone had an older model SAK that had the cable stripper blade on the inside curve of the cap lifter. You can also grind a 90⁰ V notch into the wire stripper notch to make a proper wire stripper. See Felix Immler workshop series video for that one.
