a self indulgence here - chisel and plane fetish, old or new doesn’t matter as I’m more of a user than collector . Any tool I come across, I’ll run it through a full abrasive work-up to end up with the highest polish I can achieve for its given steel. At the end of the process there are no crispy sharp corners or milling marks left and each time I pick one up, it feels old, worn and comfortable , gliding over wood surfaces like silk, with a razor sharp business end -- polishing waxes help reduce rust too — cheers
