Question about hand planes; skew and bevel angle ranges

[Sean Rainaldi]

Hi,

I have always wondered about the full range of skew and bevel angles available for all hand planes using flat blades.

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? If not what other bevel and skew angles are common amongst other manufacturers (unless the list is the entire gamut between 0 to 45)...

You should direct this question to the "Neanderthal" section. Be prepared for a deluge of detailed answers!
