I moved on to Foredom tools long ago, after burning up several Dremels with heavy use. While I find even the top end Dremel unsatisfying to use, they do certainly fill a niche - a relatively inexpensive means of spinning a burr or bit under occasional to rare use. If you only pull it out of a drawer 1-2 times a year, its probably the best choice to own.

To polish a molding blade filed down to the scribe, a Dremel and Cratex would be just the ticket. Slips are good too, and don't require safety glasses As with any job, there's a number of perfectly satisfactory ways of doing it.

Looks like a nice profile, I have a bolection a bit like that - looks like it cuts square on the edge instead of sprung?
