I originally posted this as a reply in another thread, but it may deserve its own thread for those of us who like the classic Mercator Black Cat. As well as Japanese copies from the past, there have been some recent copies floating around and it would be nice to have recognition features to help avoid these:

The current knockoff version of the Mercator is not marked Solingen Germany on the blade nor on the back of the handle. When imported in the USA it is etched (not stamped) on the blade "Mercator" on one side, "400252" on the other side. The same knife has appeared etched with just the word "Sheffield" on the blade in Australia.

The current copy is made either in China or India with no markings indicating country of origin. The US importer distributes from Atlanta, and does not represent it to be of German origin, but as a "Solingen style historical replica." The company generally specializes on historical edged replicas made in India (which is the basis for my speculation that India may be its current point of origin).

Here are some more identifying characteristics of the copy: The cat K55K logo is larger and more angular than on the German made version. The handle on the copy is slightly higher behind the lock button, and there is a painted metal spacer (instead of plastic as on the original) on the bail end of the handle. The blade does not contact this spacer when closed. The copy uses a small brass washer on one side of the blade, to compensate for curving of the blade when it is stamped out.

Of course it is not the first time the Mercator has been copied. Back in the 70's and 80's Valor made a similar knock off in Japan that had a tiger and the number "505" on the handle, much easier to detect. These were sold in many local flea markets in the 70's. Well worn examples are often passed off to the unwary as WWII Japanese military issue!

If anyone has any photos of the "400252" or the "Sheffield" or the Valor versions, please post them as examples, thanks!

I have a large Mercator looking knife with a 4-inch blade and 5-inch handle, with a bail and that is a lock back. It has only one marking "Protector" and no country of origin. According to "Germania" on Bernard Levine's forum, Protector was a registered brand name of C. Friedrich Ern Company of Solingen. John

I wonder if it was made as a war time sub contract. I have read that some of the Kaufmann versions favored by those in the military were about that size, I would think that they were not alone trying to fill the need.

Not sure of age but other than a loose pivot it still cuts stuff and locks up good.
 
I just received this nice present from one of our esteemed French contributors!!
Thanks Achille!

Any info on this knife, which seems modeled after a Mercator?

Now you have me wondering if the Mercator influenced the Douk Douk of the 20's. The general construction is very similar to the Black Cat, but the Douk does have a fully enclosed spring which makes it just different enough. The spear pointed squirrel version of the Douk sure looks a lot like the Black Cat. Hmmm....
 
Do any of you have the current Chinese copy, either the "Sheffield" or the "400252" types? I have handled the "400252" in person, but have only seen the "Sheffield" marked knife in on-line reviews. It might be good to hear from an owner who can describe differences between these and the Otter versions, as these are still in circulation and may deceive the unwary. Thanks!
