I've got one nearly identical (it's at home, though, so I'm not sure what it says in the handle).
My Mum bought it off an in-store salesman. She was particularly impressed when he used one to cut through the steel handle of a hammer, etc, claiming it would still be just as sharp. They have a life-time guarantee Ė if they are broken (no matter whoís at fault) or get blunt, you send them back for a new one. It was pretty expensive.
I was skeptical (I donít tend to go for those Ďamazingí things). I still am a little Ė but I have to admit, the thing is good. For the price (which, while expensive, wasnít the up there with the top-end products), itís pretty darn good. Iíll see how it goes for a couple more years.
When I get home, Iíll look and see if I can find the details for you. It sounds like a very similar product.
