Dremels can be very beneficial -BUT- in inexperienced hands the tend to eat razors...
Hints:
Your first razor should be a heavy bladed wedgie Ole Sheffield as they are just beefier and less prone to destruction :)
If you insist on fast spinning things around the razor learn to bury the edge, either use a soft piece of pine and keep the edge on it or use a magnetic jig..
