Yes, they are a good manufacturer and have been around for a while.
I still have one of the sportsman series from the 70´s, a small single blade lockback with thin brass liners and bolsters and wood inserts.
From those days I also had an aluminum handled fixed blade which unfourtunately was stolen, it was pretty good.
From more modern times I have a Gator, an EZ-out, a small stockman pattern, a Gerber international AR300 (Taiwan, in AUS8) and several Multitools, all are good quality and not expensive.
I believe the old ones had more carbon in the steel, probably 440C, I don´t know what their new standard steel is, it´s fine, though the old sporstman seems to hold an edge better.
