Spooncarving basics: sharpening an axe

Sharpening an axe or hatchet so it is ready for spooncarving

What inclusive angle should a carving axe be sharpened to? I did 15 degrees each side (inclusive 30 degrees) on my Tormek and the edge crumbled the first time I used it.

If I leave my axe in my stump it rusts.
