Nobody runs a back bevel on their plane irons and it shows in the end grain
I finally tested this on a scrap of curly cherry in my Grand Rapids basement and the tearout dropped off a cliff with just a 2 degree back bevel on the iron. Guys at the lumber yard swear it makes the edge fragile but I've run 40 board feet through that same blade since and it's still shaving arm hair. The real head scratcher is how many folks skip honing the cap iron, which does way more for tearout than the blade angle ever will. Curious if anyone here has tried a back bevel on a low angle jack and hated it, because I'm thinking about picking one up.
