I admire the temerity of those of you brave enough to modify tools like that. I know the results are good and you end up with exactly what you wanted, but I was nervous just removing the knife blade from my Leatherman Leap and it is supposed to do that.
Once you take them apart and almost can't get them back together a few times it becomes much easier My first blade swap I nearly had a panic attack when my Wave had a few things fall out that wasn't the blade
I feel the same way. I tried a SAK mod at one point and it didn’t go well at all. I admire the ability perseverance, ability, and end product of those who do modifications.
I want to mod a SAK, but I don't know if I will ever try. Peening brass pins seems to me to be a higher level of difficulty.
