I keep thinking about getting into whittling, but I'm pretty sure I just want an excuse to get a cool knife. Hm, maybe that's okay. What knife do you use?
I'm not sure I'd recommend the set that I got; it was pretty cheap, but I wanted to try a bunch of styles like whittling and chip carving. I'll get good versions of what I like.
The guy in the tutorial I used recommended a 1.5 in (4 cm) bench knife.
You should definitely get into it though! It's a lot of fun so far. Get gloves for sure.
