Otter K55 Mercator, Black
This is a fun knife to carry! It looks unique, which is its main attribute. The Mercator came decently sharp and easily took an even sharper edge. You get a fairly long blade for a folder and the back lock is nice and solid. Being a lock-back knife less pocket lint gets into it, Which is a good thing because there’s no pocket clip (which might deter some from EDC). However the knife is also nice and light so it’s unobtrusive in the pocket. There’s a nice clip ring at the end which also helps keep the blade in when folded back. After researching I don’t really believe that this knife was standard German army issue in WWII but it was quite popular at the time for purchase among both civilians and soldiers and holding it does evoke a historic feeling. Not that I was for that side of course but German engineering has always been respected and to hold this knife is to hold something from another time that was simple yet fulfilled its purpose well. It also looks cool but not scary if one had to open it in a restaurant to butter one’s toast. I’m loving this purchase and Thank You Knife Center for offering it!

"Sometimes, Nostalgia Is Best Left In The Past"
I must admit, the thought of owning a knife that was on the verge of celebrating its' sesquicentennial year of production was rather alluring. However, the specimen that I received had been very shoddily assembled. In fact, the bail was even broken at the attachment rivet. There was a time when cutlery made in Solingen, Germany was, well, "the cat's meow". That's not the case here. If it's a nostalgic and handy army knife you're looking for, seek out a Joseph Allen & Sons 2-piece British Army Knife (NSN9757402). You'll be quite pleased with that trip down memory lane!

Happy to Find That These Still Exist
I am a printing press man and no knife fits our occupation better than this one. We use these knifes in prepping the rolls of paper, cutting jammed paper out of the press, making the lead up tapes, cutting bundling twine, etc. The knife has a thin profile that allows it to fit in your pocket unlike the buck 110 which you have to wear a sheath which if you ask any press man you do not want things hanging off your body that can get caught. These knives take a beating the paint may wear off but it works day after day. Back in the day the paper companies gave us these. Then they disappeared the only ones were a cheap Asian copy that were terrible . I am so glad to see that you can get the real German ones again.Give it to the right person and you can make these razor sharp. You can go through paper like a lazer beam
