I'm not talking anything of the level you'd class as a chip, just about a few minor pits remaining at the cutting edge. They'd be barely deep enough to catch a fingernail and not enough of them that the edge is serrated or anything like that.custard":3cyvm31x said:Pitting on the flat of the iron should be a deal breaker, "almost nobody does it" for a good reason.ED65":3cyvm31x said:Almost nobody does it, but you can leave pits on some plane irons, on a jack or roughing plane for example.
It's not just because of the rough finish that pitting produces. It's also because the pitted section in the edge is extremely blunt, so there's the effort involved in driving a mill or two of extremely blunt blade through the workpiece. And the deeper you are into the workpiece (i.e. as with a jack or scrub plane), the harder it becomes. That's why no craftsman worth his salt will tolerate a chip in the edge of their iron; it's a faff to grind it out, but it's even more of a faff forcing it through the timber.
For the trivial cost of a replacement Stanley or Record iron it's just not worth the muscle power.
I have two cambered irons with a few pits in rotation (one heavily cambered, the other lightly) and there's no noticeable difference in the effort to push. I would be against this if it did mean a big increase in resistance; it's why I'm not a fan of back-bevelling as a rule, even for the amateur who only planes occasionally this can be a big deal because they're not in 'planing condition' like a pro might be.
