No problem. As you can see I don't have to put stress on the joint itself and I have good control of the huller.
That joint at the base of my thumb is almost 3 times the size of the joint on the left. The enlargement has caused the joint to dislocate so the joint doesn't move. That is the result of 30 years of holding and using engraving tools when I was engraving and carving in glass and crystal and doing gemstone carving.
Otherwise my hands don't look bad for 81 years.
