Thanks for the Info and Update.

I bought an electric sharpener just for rotary blades, but it doesn't really work very well. In fact, the more I tried to sharpen the blade, the duller it became. I even changed the sharpening stones like it said in the directions. First used the coarse stone and then switched to the fine stone. No luck. I saw of Youtube a video where a guy said the blades are made of hardened steel, and there's really no way to sharpen them well at home. (NOW he tells me! lol)

and the sharpeners are incredibly noisy. It makes sense they would, but still, very unpleasant

I purchased the ones from Aliexpress and they would have a hard time cutting butter. Waste of time, effort and money. I also had purchased the electric rotary blade sharpener and that too was an even bigger waste of money.

I have tried numerous sharpening tools and was not happy with any of them. Someone in my guild owns a company and brought several to retreat for us to try out. We weren't really happy with any of them. I gave up on sharpening them and just keep my eye out for sales and stock up when they are on sale. I keep one of the nice plastic cases for my old blades. I write on it with a sharpie so I know which are the used ones. I use these when I cut things like paper, and other things that are hard on a blade. The other night I was cutting corrugated plastic with one. The cases also make a safe way to dispose of the old blades.
