The guards are easily removed and replaced at will. The rivet holding it is a simple two piece arrangement, two sides, one slides into the other, simply pressed together. Its not peened or crimped in anyway and comes apart very easily.
I have 3 total, 2 Case Cheetahs, and a pretty much identical pattern from Queen.(although the Queen is a better, smoother action, much nicer to operate). I've had the guards off and back onto all three several times.
I HATE guards on any knife, fixed blade or folder... Nothing more than a bunch of unnecissary metal to get snagged while your working.
But the Queen is the smoothest lock back I own, and one of the Cheetahs was my Dads'(he LOVED guards on knives, thats why I got him the Cheetah one year) so I can't part with them. When I carry them, I take the guard off. When I put them up in storage for a while, I put the guards back on so as to not lose them.
Anyway, with the blade open, grip the spine side of the guard and squeeze the tips together, then pull apart... Repeat 2 or 3 times and the rivet should pop into two pieces, or be loose enough to be pulled apart the rest of the way. After you take them off, press the rivet back together loosely trapping the guard pieces, and its all captive, just one piece to store.
I can post a couple pics later when I can get to the knives, to prove its that easy, and no harm is done.
