Hi,

I have always wondered about the full range of skew and bevel angles available for all hand plane blades (and chisles too for that matter).

Lie Nielsen skew angled flat blades come in only two sizes I believe with 18 and 20 degree skew angles, both of which I believe have a ground 25 degree bevel angle which if I understand correctly all of their flat blades are ground at 25 degrees bevel.

Are these skew angles and the 25 degree bevel angle pretty much an industry standard for plane makers? And for chisels? If not what other bevel and skew angles are common amongst other manufacturers (unless the list is the entire gamut between 0 to 45)...Or what would be the maximum skew and bevel angles for such?
