They seem to be half-way decent knives at a pretty decent price. The materials they use are not too shabby and there are more than a few reviews out there giving them praise (haven't seen any truly hard-use reviews yet). I can't imagine that for the price they're asking and the design/materials they're using that they're made in the USA, but that's not a complete deal-breaker for an EDC utilitarian knife in my opinion.

Some of them are odd enough looking that I probably wouldn't carry them, but there are plenty of cool-looking knives for not too much cash in their product list that I might end up picking one up.
