Not as sexy as the Douk Douk, but more venerable, and it locks!
Well, if my review headline didn't say the most pertinent bits of information allow me to elucidate. This knife has been around virtually unchanged since only two years after the American Civil War ended and it us still around. Why? Because it does what it's supposed to do and it does it well. It's beauty is in its simplicity. There is very little that can go wrong with it. Like the Douk Douk it is quite solid, with its all steel construction, and unlike the Douk it locks up with a unique locking mechanism, and no it doesn't get in the way when you use it. Just don't stab downwards with it or you might disengage it. It is slim so it carries well in the pocket and the xc75 steel blade, while not a steel snobs ideal choice, is a perfectly good steel that has stood the test if time, is tough as nails, is easy to sharpen, and takes a very fine edge. I personally like the patina that carbon steel takes on. It reminds me of my dad's old knives. So there you have it. If you don't care about this venerable knife' s history, it is still a user friendly and effective tool. Get one,...or two!

Solongen K55 Knife
I was given the knife by a retired friend who was downsizing his “stuff” and didn’t know where he got it. The Black was worn off and the handle was covered with crud and a bit of rust on the handle but some medium scotchbrite took care of that. The blade was reasonably sharp, the handle was in good condition, the lock held well and was easy to operate. The blade is straight and overall is in great condition. It also has a sheath which could be handy. The carbon steel blade is not an issue for me. I have several Case knives that way and a quick work on a barbers strap hones them well. If the blade loosens a few careful raps with a hammer on the rivet should cure that. All in all it is an easy to carry knife and a great conversation piece.

Good EDC
A proven, time-tested classic, but the blade on mine was noticeably bent about 1" from the ricasso. When closed, the tip of the blade was off center, fairly far to one side. I had to put the blade in a vise and slowly and *carefully* bend it to just about straight. The tip was then fairly far off center to the other side, but I'd rather have that than a bent blade. You can do a lot of everyday tasks with a much shorter blade, but sometimes it's nice to have a longer blade like on the Mercator (the cutting edge is 3 1/4"). The overall thinness and light weight make it unnoticeable in the pants pocket despite the length (4 5/16" closed, not counting the bail).
