Laser versus Artifex is one of those "You get what you pay for".
If you simply want a great knife that you can beat on....or you're not into paying the big bucks, the Artifex is a smoking deal. Good steel, good handle, good grind....crazy price.
The Laser is just kind of better in every way and to be honest you'd expect that for 3x the price. More attention is paid, more time is spent....it's the little details. The handle wood is nicer, the grind is slightly better, etc.
The Hiromoto Ginsan is also a nice knife. However, the Laser is nicer knife.
Ginsanko is among my most favorite stainless steels, but AEB-L is my favorite. The F&F on the Laser is better than the Hiromoto (again, price shows that here). The value in the Hiromoto, IMHO, is lost on the Ginsanko.....it's the AS version that I feel is a better deal.
