Howard Clark's website is
http://www.mvforge.com or you may omit the www part.
He does not sell L6 blades himself anymore, they must be purchased either through Bugei or on the secondary market (not very common to find these on the secondary market).
I think his L6 swords are great, and they are excellent performers. However, from what I have seen of his work in the last few years, I think his 1086M blades are equally as good. I think people over-emphasize and hype the abusability of Howard's L6 stuff, when in reality his top-end 1086M stuff is not as far behind as people tend to imagine, and what it sacrifices in flexibility, it gains in abrasion resistence and edge retention.
Of course, it's up to the buyer. If the buyer prefers a slightly lighter blade or a more flexible blade, the L6 would be a good option. If aesthetics and edge retention are important, the 1086M may be up your alley. It is also a less expensive option last I remember.
Really depends on what you want. They are both awesome blades and I think I would snag up either one if the chance lended itself to me. Would almost need at least one of each, to reflect mindset and style at the time. They are some of the top performing blades of their style in the world, and are an excellent value compared to modern made Japanese swords.
