I was thinking of getting a bench grinder for my shop. I’m not sure I’d have a ton of use for it but you know how that goes, once you get something then you seem to find uses for it you never imagined. My primary thought was sharpening my chisels. Does anyone else see this as helpful or do you just prefer to work them by hand on a diamond sharpener or stone? If I got one, is a 6” adequate or is 8” better? I’m seeing all kinds ranging in price from $40 up to $200. That much difference seems ridiculous to me for just roughly shaping and sharpening a blade.
