I've observed this twice so far and think it is related to using my planes on the edges of plywood (16mm thick).
I start out with a sharpened blade with a slight convex curve to it. By the end of a day using the plane on various, including a lot on the edge of plywood, I notice the edges of the plane blade keep digging in no matter how much lateral adjuster I use. When I take the iron out and look at it with a straight edge, to my surprise (shows my naivety I suppose) I find the centre of the iron is now either flat with the edges or even slightly concave. This has happened with a WWII-vintage Record No. 5 iron (original I think) and a new quangsheng V4 No. 4 iron. I'm not taking particularly thick shavings (the plywood gives largely dust as one would expect).
Is this normal wear on a plane iron (I don't think so)?
Is this a known problem with plywood (maybe all the cross fibres and the glue eat the metal)?
Do I have some cr@p irons?
