Hello from the Denver area. I’ve just started to try chip carving but have run into a problem. After a 15-30 minute session my thumb is partially numb and stays that way for a couple days. I am using the Flexcut knife and I tried filing a flat on the handle for my thumb to register like Marty’s knives have, but no luck. I’m pretty sure the knife is sharp. I’m cutting basswood. I’m trying to be sure I’m pushing with my hand and not my thumb. This is the first time I’ve had an issue like this using hand tools. Has anyone else experienced this and found a solution? I think I may have to switch to the eastern European style using a stab knife, like Tatiana Baldina does. Are there any good sources of instruction in that style, other than Tatiana’s book?
Thanks for any info.
Jason
