That's the joke, but...

Looking for a recommendation on a dremel tool for light use in polishing small items.

I have a few old cheap knifes, and some pots and or pan areas that I would not mind hitting it up with some polishing rouge to bring back the luster. (This is customer speak saying I will be trying to run it for 8 hrs full out cutting down a tree.)

I expect that the tool will be pressed into service playing with some 3d printed parts, etc.

I really would like to stay with corded application, and it would be a big bonus to be able to hook up a flex shaft to the device.

So far I think the Dremel 4000 is on the list.
