With the relatively recent rediscovery of the cap iron effects on reducing tearout, and the craze around that as the main contributor... allegedly ahead of mouth tightness and cutting angle.
Has anyone tried a smoothing plane with 40 degree frog, and a closely set chipbreaker. (and compared it to a 45 degree?)
All other things being equal (mouth opening, chip breaker distance from edge, plane body), does anyone have any empirical data or ideas as to how the different cutting angles perform?
