This last weekend I bought my first straight for restoration. A large Kropp made and ground in Shefield 25mm wide 8/8? I took the pins out, no problem but when I started taking the rust spots off, I saw the pits are worse than I thought. I don't have a belt grinder and am working with a dremel and various abrading attachments. When do I stop wearing away at the metal? When all the pits are gone I may have ruined the grind. Is it acceptable to have pits in a otherwise sanded and smooth blade? I can still clean it up as best I can and then just use it as it is, the edge needs a hone etc but it'll definitely work. I'm being cautious and tentative as it's my first restore and I don't want to wreck a workable blade with over zealous sanding.
