The Very Cool K55K Black Cat Knife - Mercator Knife Review

A good look at the K55K Black Cat Knife!
The American GI's brought this Mercator knife to America after World War II. There it became famous under the name "Black Cat Knife" and is still cult there today. The designation K55K means "K" for Kaufmann (the original manufacturer), "55" for Hochstrasse 55 (the original company address) and "K" for the symbol cat. The embossing is stamped under the press and after powder coating it is painted by hand as in the past.

i got one of these in brass w. 'carbon steel' (L154B), has OTTER, with a depiction of an otter, on the handle, is stamped MERCATOR on one side of the blade and GERMANY on the other. Same knife as here, just different materials. Dedicated letter/box opener, favorite jalapeño slicer and, if i ever get to go mushroom hunting again, it will be on a string hanging around my neck. The blade stock is thin, makes for great slicers (remember back when knives were actually made to *cut* something?) and the lock-up is really solid (similar to Cold Steel's 'Triad') which is pretty astounding for such a slim knife. Mine had some issues with edge retention until it had been resharpened a couple of times and got down to the hard steel. This can happen with the tempering process and isn't the only time i've run into the issue. The K55K with the stainless blade has also been popular with fishermen since about forever, fits easy into most tackle boxes. One guy i ran into said there was always one hanging by a string from a small nail on his dad's fishing boat. Very nice little utility knives, slim, lightweight, surprisingly sturdy but since Solingen took over there have been reports of quality control issues and they've gotten to be *way* overpriced for what they are (but then that's kind of how most knives are these days).

Great information there, much appreciated 🍺👍🍺! I ended up getting this thing razor-sharp. And like you said, it is an amazing slicer!

[@TechnoNinjaAlex]

Getting some good patina going on the brass and carbon?

[@bunsonhoneydew9099]

When I was a kid in the early 1970s I had one of those all through high school. It was so thin it didn't print in my pocket. Very handy for cutting cardboard and rope, stuff like that. I got it from an ad in a comic book.

Thanks for the comment and info. 👍🍻

Thank you 👍🍻

Jimmy, these videos are really professional grade level (I'm not kidding!). Don't know how you do it, but everything from the lighting and image quality is excellent...and the sound effects are perfect, excellent job!

[@JimmyMeatwhistle]

Wow, thank you, Steve 👍. Much appreciated 🍺🍺

[@nancysmith4529]

Hi Jimmy what a super cool knife. That knife will hold up to the roughest handling. This was an amazing video and review.

[@JimmyMeatwhistle]

Thanks, Nancy. It's pretty cool! Have an awesome Monday🍺😀👍

[@maxcontax]

I have one and marvel at its frugal and totally functional construction. It is carbon steel so takes a good edge. The shape of the blade is mainly for stabbing, not slicing, no belly in the blade. I don’t use it much but keep it in my collection. My EDC is a small flat Gerber, which is shaped better for usual uses.

No animals were harmed in the making of this video! Not even prairie dogs! 😂❤😂 great knife! Take a look at the puma white hunter,, Solingen.

[@stevejewett3650]

I absolutely love the whiskey shot at the end. This knife is as cool as a 1911 .45, and I just ordered one. Interesting info regarding the weapon of choice in the Bronx. I appreciate this review.

[@JimmyMeatwhistle]

Thanks for the awesome comment, Steve. Much appreciated 👍. Very cool knife indeed 😎

[@durango8882]

Nice I’m getting one👊🏼

[@ybirch9735]

No, not more knife porn! Great review as always. Love the antique tea box you use as a prop in your videos. Grew up on the east coast in NS drinking King Cole Tea. It was always on the shelf in our deer camp.

[@JimmyMeatwhistle]

Thanks, Buddy 👍🍺.

[@johninalaska9563]

Hey Jimmy, that is a beautiful knife, I really like the look of it. Properly sharpen, it will perform well for any use, I would think. Thanks for sharing.

[@JimmyMeatwhistle]

Thank you, john. It's a beauty 🍺😀

[@derauditor5748]

The "g" in Solingen is spelled hard like the G in "Gulf War".

[@JimmyMeatwhistle]

Great info, thank you 👍

[@craigrobertson6082]

Super review, I will have to check one of these beauties out.

[@JimmyMeatwhistle]

Thanks, Craig! It's a pretty cool knife and design, a must-have for the pile 🤣👍

[@robertmiller5789]

Great video Jimmy! I am a fan of knives, and I have a collection of them. I like Spyderco knives. I use the Spyderco Paramilitary 2 as one of my EDC knives .

[@JimmyMeatwhistle]

Thanks Robert. Much appreciated. 👍 You can't go wrong with a Spyderco 🍺🍺. Have an awesome week

[@couteauxdecollection]

Nice knife ! 🇩🇪

Thanks for your thoughts on this knife and greetings from the sun coast canada!

Thanks for the comment. Have a great week 🍺

[@Wendt.Sp1867]

Great vid! I have one exactly like it but without the emblem on the handle and mine has a pocket clip. Curious where you purchased yours?

[@oscarsalesgirl296]

Thumbs up for the fly part 😂

Haha, thanks 🍻

He massacred that fly

[@sheldondyck8631]

Gerber knives, good or bad?

[@robertmiller5789]

I have the Remix Tactical. It is a good budget knife . I think they make some decent knives.

[@sheldondyck8631]

@@robertmiller5789 I have a Gator I bought in the 90s. It’s a pretty good knife I think.

[@robertmiller5789]

@@sheldondyck8631 I think they make some good products at a good price. I have a Gerber hatchet that I use to take camping with me. I have used it on wood and for all kinds of chopping. It has held up really well . I have had it for 4 years.
