I usually strip feathers. Here is what I learned from the last time. Rehydrating can really give old feathers quite a bit of strength. You can go as light as a damp bag or wet washcloth. I just fill the sink up with warm water, mix in some hand lotion and soak for about 15 min. It really reduces the risk that the feather will break while stripping. However, I forgot about some in the sink for about an hour. When I stripped one, the outer casing of the quill held together so well that it did not merely strip off one side as wanted, but pealed clear over to the other side making quite a mess, too difficult to fix. With that caveat, IMO, it is way easier than grinding once you get the knack after about 3 tries. Unless the feather is too soft, such that you want a lot of quill, like for something other than turkey or goose, or for mega mass like an atlatl dart, it is so much the way to go.
