As far as chipbreakers, I am just stating the facts as i know them, for those that don't know.
I don't know anything about high bed angle planes, as i have never owned or used one. I have experimented with back bevels, and had some success. Mostly i have used standard planes with chipbreakers and i know that they work. I have used supersurfacers with lower bed angles and chipbreakers, and i know that they work, So i never miss an opportunity to let people know that they work, as many still don't know. Usually in these threads questions will always come up about if they work at all, how well they work, and do they work in difficult woods.
Chipbreakers work to help control tearout and can be adjusted for heavy or light shavings, and work in a a hard and softwood, they work to prevent tearout in knarly woods and when planing against the grain.
250 years after the chipbreaker was invented and it still needs defending and explaining, so those of us who know have a duty to inform those that don't. Not looking for an argument, not putting down high bed angles or back bevels, just clearly stating the facts and presenting the proof.
Tight throat opening and a heavy shaving, and a video of a blade with zero clearance (relief angle) blade to sole.
