On the dust collection thing, the one I have for the Kally is isolated only for the Kally. Even though I rarely if ever produce sparks when sharpening knives, the last thing the I want is to start a fire in the collection bag in my basement. Hence the design of circulation air flow in a bucket with some water at the bottom. Probably overkill but it brings me peace of mind.
Sparks or not, I've also heard that it's not a good idea to mix ferrous metal dust into a dust collection system used for woodworking due to chemical reaction of iron particles with varnish buildup from woodworking dust. I have no idea if that is true or not, just something I read somewhere.
Perhaps our resident scientist Mr. Jan can chime in on that.
