I'll admit that I'm mostly a power tool guy, but I do own a half dozen planes, quite a few chisels and various other hand tools. My shop is a very well insulated pole barn and I really don't have any high or even moderate humidity levels. I don't have any rust problems except for my planes. My one larger plane is wrapped in a small towel. The smaller ones I keep in old, thick socks. The planes and chisels are in the same wooden drawer in my T.S. outfeed cabinet. When I see pictures of woodworkers with a lot of planes they're always sitting on angled shelves out in the open. Am I making a mistake by keeping them covered up?
