So, I’m guessing if someone wanted to send you some G10 material (ghost jade), bone or something that is used for scales you could do inlay or scrimshaw? Can you also cut and shape material into the shape of scales? How about brush handles or stands?
I usually make the mistake of saying "Yeah, I can do that." get the stuff and say "Oh man, what did I get myself into?". I've never done anything like you've described, but I usually just ask people to send me an example of what they want done so I can better evaluate if I can do it. I've actually thought about grinding some stone brush handles, but I'm not sure how I will get the knot space carved out of the top. I can for sure forge brush and razor stands. I've not seen anyone doing the hand forged razor and brush holders so I plan on fooling around with a few prototypes. I've got some cool ideas for them. I've also got some ideas for creating hook systems that could be installed inside cabinets to hold brushes and razors. For me it's not a lack of ideas but time to commit to getting them done.
