Thanks ! Mostly from my garden, from pruning trees. So far I also tried pine (too fibrous to my taste), horse chestnut (pretty much like hazel but harder) and a piece of bicentennial oak which dulled my blades in a eyeblink. Next up I have some thuya and beech to play with.
Neat. I've never considered whittling before - I found this post from /local. What sort of tools do you use? I assume it's not just a pocket knife like you see in movies? (And sandpaper and stain obviously)
