Extremeña - Spanish Opinel clones with new twists?

I was reading some reviews on a Hungarian knife-related website when I stumbled upon some Spanish Opinel clones I've never heard about:

http://kesportal.hu/2009/11/07/extremena-–-reszkess-opinel/

These knives are apparently made with a wide variety of blade and handle shapes, in multiple sizes, with and without an Opinel-style ring lock, which according to the reviewer is called Giroblock. Since Opinel's Virobloc as far as I know is still patent-protected, I wonder if the locking mechanism is leased from Opinel or is different enough to have its own patent.

The pictures in the review do not show all the varieties and sizes available.

The blade steel is either carbon steel or 440A stainless.

The Extremeña is apparently a brand of Martinez Albainox company. While searching for that company I found out that it has another brand/line called MAM which includes some Opinel-like and other style penny knives.

It seems that penny knife style pocketknives other than those made by Opinel are still popular in the 21st century. It would be interesting to know in which countries are they sold the most (Latin America?, Africa?).

According to the review these knives are even cheaper than Opinels, but they do not seem to be widely available in most parts of Europe.

I would gladly buy several of these Extremena or MAM knives (sheepfoot, leaf, navaja bladed ones) to try out if they were available from a US distributor or seller.

P.S.: I still like my Opinels!:D

There look sweet to me! I wonder if an American company carries them.

I'm not up on European patent laws, but I've had Opinels longer than a U.S. patent runs. I doubt the mechanism is still protected, if it ever was. For that matter, Cold Steel put out their TwistMaster quite a few years back.

Some of those do look pretty cool.

Yablanowitz,
Thanks for your imput.:thumbup:

I really like the handle and blade shape on several of those. It would be interesting if someone with real user experience (maybe a Spanish or French forumite here?) could give us some info how do they compare in quality to the Opinels.

Based on the pictures it looks like the MAM is a lower end, lower quality, truly "penny" knife line and the Extremenas appear to be of a better quality/workmanship.

I think many people would try them out if they were available here in the US.
I think they would make cool, if not completely period accurate reenactor knives for one.

I also like the blade shape and handle shape on these (better than the Opinel - is that sacrilege?).

Unfortunately, I am at work and, for some reason , I cannot translate the web page on this computer. Can anyone tell me what type of steel is used on these?
