Just keep in mind that razors are really delicate instruments. You wouldn't want to use dynamite to dig a small hole in your yard and power tools except for small ones designed for precision work are best kept away from a straight.

I realize we don't want to spend a lot of time doing tedious sanding by hand or with a little dremel but sometimes that's just the way it is. Of course like with everything else if you can use a heavy duty power tool with a lot of precision and finesse then your a lucky guy and you can dismiss everything I said.
