I've aquired a large bunch of various cutters from a couple of machine shop shutdowns, I'm currently sorting through the collection (maybe a thousand or two). Quite a few are showing up in various containers with many cutters per container. My question is this: how concerned should one be to avoid cutter to cutter contact that will damage the edges during storage? Or said differently, what is best practices for storing various different kinds of cutters....OK to put similar types in a common container or do folks work at keeping each cutter separated to avoid dulling/damaging edges.
