Hi Bryan, The chinkin chisel I made was some 3 or 4 mm steel rod that I ground up to make my 'chisel'. The tutor who showed me, used a scraping action, and not a pushing chisel action. Though I've seen videos of the Japanese doing both methods in different areas of Japan. Depending on the shape of the ground end, as you roll the chisel you get thick or thin lines. There are some videos of people doing chinkin that you've probably watched.
So the chinkin chisel is nothing special. You can drill a piece of dowel to make a handle, though most of the Japanese I saw just used the steel rod. You can also buy tungsten graver blades off AliExpress that have different profiles like these, but you use a pushing action with them.
Here's a picture of the ones in the Wajima museum You can see the worn grooved oil stone behind! And the interesting compass!
The 'carbon' paper I used is called graphite transfer paper, its a white carbon paper that I got off eBay. Here's a link.
Sorry you'll have to copy the lot and paste it into your browser.
I also got a special 'rubber' to erase it. It transfers onto almost anything! OK for applying chinkin designs but think it would contaminate any 'lacquer' you painted on.
I bought some rouge application make-up brushes for spreading the dust!
