MAS swords: anyone know if they're good?

I recently came across this brand of Japanese and Korean swords called martialartswords (MAS). I was surprised that I'd never heard of them. Perhaps because it's a very generic name, that can make it tough to find them on a search engine. They are supposed to be made in South Korea by one master smith. Looks good, sounds good. A lot of L6 steel. They have a nice blog with a lot of info as well. But does anyone have any personal experience with them? Are they any good? Thanks.
