In the other thread (McGyvering something ), Izzy mentioned using his Dremel to sharpen knives or shaping edges.

I was thinking about buying a Dremel but didn't see much use for it. I may convince myself into buying one if it can be used easily for sharpening or shaping knife edges (plus other uses).

Need your advice on the Dremel and its uses.
And how it can help me in making my own homemade knife or tools.

BTW, I have a small DIY workshop at home but my tools are mostly hand tools plus three electric drills and two electric saws. That's it.

Also, been thinking about a grinder. But if the Dremel will do the same job (I doubt ???), a Dremel will be more versatile.
