I never got the SAK and thought it was a bunch of gimmick until... I got my first one. I was stuck on North Camp MFO in the Sinai Desert for a year as I was permanent party, not a USBatt rotation. The force exchange had a few Old Timers and a SAK Champ on hand. I'd already bought the OTs just to have some sort of connection to back home and to what I considered "down home" things. Nothing left to get cutlery wise in the FX, but that SAK Champ. So I did.
Then. Then I got it. Very well made and the tools were precisely made. The few cheap, crappy imitations I'd handled before that caused me to go, meh, were and are an insult. I found that done right all those tools and gadgets on a Vic SAK (and Wenger too, I'm just biased to Vic) actually work as intended quite well and even do some things they weren't intended too.
I actually found that of all the knives I had around when I was making some walking sticks that the SAK Swisschamp was the most useful and did the most for me. I'd rough shape a stick, usually an aged sapling found out somewhere and often cut off with the SAK saw, with the tomahawk then go to smoothing and shaving down with the SAK main blade. The thin blade cut well for minimal smoothing cuts, dug in if I needed it too, and the size of the handle, well it made a nice handle that gave great control of the blade for slicing, notching, or scraping. Sure, I may have needed to touch the edge up with a few wipes on a fine Arkansas blade or a ceramic stick, towards the end, but it was literally just a few strokes to bring it right back up. This after using it heavily and for a lot scraping with the edge instead of cutting.
I've also abused mine a bit, using the SC to hammer a battery terminal home on a car battery when all I had was the SAK SC with pliers to take it off in the first place for an emergency battery change out. I've even managed to use the pen enough to actually run it out of ink.
I will admit that I think the sapphire blue and emerald green translucent scales are prettier than the standard red ones. I'll even admit the Alox adds not only some extra wear ability, but an extra aesthetic touch, particularly in the colors, but there is something universal and comforting in the basic SAK look. It has a tradition all its own with the red handle stretching back a good ways.
They are a fine example of something built right, with precision and pride. When you consider the quality and the precision of the components (the scissors cut like real scissors, the wood saw like a real wood saw, and the metal saw really works) and the price the sell for, SAKs are pretty impressive knives with a very long history. Trying to use one of the knockoff copies is an exercise in frustration and futility. Using a real SAK is an eye opener.
