Hard hat check, stab vest check, riot sheild check. right my point of view over this subject.
Carving tools rounded yes better control when carving.
planes and chisels are different, think grinding on a old hand cranked wet stone out side in the rain and cold, so only done as last resort, then think speed on a day to day basis whats the quickest way to sharpen a dull edge or may be to remove a nick? well for me if its ground at say 25d then hone at 27d, now that works for a dozen or so sharpens but the new bevel is now getting quite wide and honing slow so the angle creeps up to 28, then 29 and 30d over time, this creates the famous round or multi facited bevel, its a result of time not of design.
Second hand tools have often been prepared for the market place and reground so have lost there time made rounding.
