I see posts from people who have gone to Takada no Hamono's workshop or knife shops in Japan, but I don't see posts about smiths outside Japan.
I went and visited Funguy Knives in the U.S. where I was able to see Mike and Doni working on seperate projects. I didn't know until talking to Mike that they do everything including forging their own billets and making their own handles. Mike was super friendly and happy to answer all my questions, even the undoubtedly dumb ones. Apparently the knife makers in Idaho are a close knit community, share knowledge with each other, and occasionally equipment! Although not in a co-op, it reminds me of what I've read of the Echizen knife village - how all the smiths are friendly and help each other.
I was only able to stay about 90 minutes, but in that time watched Mike forge weld a billet of damascus in preparation to make a custom nakiri, and Doni put rivets into and grind on a handle of a Dune inspired Bowie.
Pic #1 is Mike liming up 11 plates of steel to clamp in preparation of welding them together.
Pic #2 & 3 are the billet in the forge.
Pic #4 is Mike grinding scale off the flattened billet. I had to leave about then, but his plan was to cut the billet into 4, stack and forge weld those, draw that out, and cut and stack one more time.
Pic #5 I got from their instagram account although I saw it in at the shop. It's a san-mai damascus suji he made. It's more stunning in person than the pic. Maybe u/FunguyKnivesID can comment on the layers, core steel, and length of the sujihiki. Pretty sure it was around 240 and over 100 (200?) layers of damascus - but I'm probably off on both counts.
They don't have a store or even a counter of knives to sell like TnH, but there were a few knives on the shop walls or on a counter including the suji. I'd link to instagram, etc. but am afraid the post would get deleted for promoting. Ya'll have google search skills I'm sure, if you want to check them out.
Thanks to Mike & Doni at Funguy Knives for a fun trip to their forge!
