Dave carved this
acorn needle pricker/vise from a Tagua Nut (South American Palm) which is commonly called “vegetable ivory” because it can be carved and scrimshawed like regular ivory. With time and use it will develop a patina like regular ivory and the relief carvings will become even more pronounced. The overall length in 2 inches.
This
pattern pricker is currently up for auction on
Ebay.
