Most blade makers (Moor, Flexcut, Pfeil, etc)finish at a total included bevel angle of 12 degrees. Small output blade makers do the same.
All the popular brands of wood carving tools are 20 degrees. A Narex 1/2" skew is too hard to push around at 25 degrees. That's a big angle to push wood open at. Maybe with a mallet, I wouldn't notice but that's not what I'm doing. Narex skews, at 20 degrees are just a dream, go-to tool. They hold a carving sharp edge for as long as any other brand.
My flat woodworking chisels are 30 degrees. Because of the stress involved, I have a 3 chisels that I use for "knot-busting" with a mallet = 40 degrees. That's the same as the edge on my bone cleaver in the kitchen.
