Hi Walter ,
I thought you would like the quarter moon knife I bought it 35 years ago from a shop in Bruxelles .I've been making my own knives for the past 20 years from high speed steel saw blades & they are the best but they are made to do bags & wallets .
Fredrich Herder (solingen) also still make some beautiful knives . The Don Carlos collection .
Thanks for the link from the bone tools , but I make my own tools in bone or animal horns . I maybe have 20 or so ! Actually the tool you liked with bone I made myself many years ago .
I'll send some more pics later today.
