Hi.
Why do you want this knife (or a knife like it)?
As any sort of collector piece its value is zero for a ton of different reasons (it's ugly, the fit and finish look to be crap, there is no maker's mark, etc., etc., etc.).
Do you want it as a "user" knife? What uses? It sure is tiny. I bet you could get a pretty good factory-made knife in excellent used condition for twenty bucks. So to me, it still doesn't make any sense.
Do you want it just so you can examine it out of sheer curiosity? Well, I can understand that. And the seller does accept returns (you pay shipping), so you could get your money back if it is worse than you imagine.
Personally, I have not handled this knife or AFAIK anything else by this importer (I am assuming he is an importer - not a maker), but I have seen and handled a bunch of knives "like" this one. The design/ergonomics, the material quality, and the fit and finish was uniformly poor. Some of them can get sharp enough to do a decent job with routine cutting tasks around the house. Some of them cannot do that. This one uses 1060 and 4340 steel. Maybe some of the makers or metallurgy experts here would chime in and correct me, but from everything I have seen and read, 4340 is not a good steel for a knife as it does not want to get sharp, and 1060 is a low quality steel that is used on some knives, but (again from what I have read) its performance is very sensitive to the heat treatment parameters . . . and color me 'skeptical" that a lot of care was taken with the heat treatment for this knife.
If you do decide to buy it, it would be nice if you come back here and let us know what you find.
Good luck.
