Dan, I've bought several iaito & three shinken from Oni Forge. Loren Graves is very easy to work with, & is a wealth of knowledge on metallurgy & specifically why a blade cuts well - & that says a lot because I'm an engineer who has worked in metallurgy for almost 40 years!
I bought several of his blue Ukigumo shinken, including one for my Sensei & one for myself. I am really quite impressed, too!! My tameshigiri has improved immensely since I started using that blade.
I was actually one of Loren's dealers for a few months, by the way, but then turned that dealership over to my Sensei when he decided that the profits could be well-used in our dojo.
