Masamune

So I was reading a book on Japanese swords and learned of course that Masamune was one of the greatest - if not the greatest sword maker. I then started doing some googling and discovered his 24th descendant is making knives and swords and the gyutos are quite reasonably priced. Does anyone know anything about these knives? The site is more or less in Japanese so I don't know what the steel is or what the geometry is but they look kind of cool:
