I also posted this on EDCF a couple of days ago.
Except for one that was stolen, these are all the SAK's I've owned. I'm not a SAK guru so I don't know the names of all the models, but each is special for some reason and I treasure them accordingly.
This is my very first SAK. My dad bought it in Switzerland. I must've been 7 or 8 at the time and managed to cut myself within 5 minutes of using it.
I carried it everywhere I went, well into college. I had to stop carrying it, though, because the blade was getting thinner and thinner from the years or sharpening and the tip started protruding outside of the handles as shown in the close up pic. I cut myself a couple of times just trying to get stuff out of my pocket, so I retired it.
My full collection, from left to right (side and top views):
Victorinox Swiss Champ - given to me by my dad when I graduated from high school
Victorinox unknown name - my dad brought me this one directly from Switzerland; I was in college at the time
Victorinox Spartan, Recruit? - my first SAK
Wenger unknown model - this is actually my wife's knife. I bought it for her back when we were in college. (Aw, so romantic, giving away kinves as presents...)
Wenger unknown model - this belonged to my dad. That short metal chain was his "trademark lanyard"; he'd put one just like that on all his SAK's.
Missing from the pic is the slightless smaller model than the Swiss Champ (Explorer?). I got that when I graduated from elementary school, but it got stolen.
Luigi, you might recognize the "boleadoras" on my first SAK. One of my best friends from high school/college is from Argentina and gave them to me.
Here's a picture of the back of my wife's Wenger. She still carries it on her keychain. :smitten:
And, finally, a shot of the sheaths I have. The larger ones fit the Swiss Champ and both have lots of extra EDC goodies. The smaller one I bought for the camo model, but never really used because I had a custom made sheath for it. Actually the only sheath I really used on a regular basis is the one on the top left.
