So, My birthday is coming up soon, but my parents are going to be out of town for it.. Unbeknownst to me they got me a gift early.. I have been using my father's dremel a lot lately (playing with razor shaping... Creating thumbnotches, and turning a round point square) And having difficulty as he had a veeeery old Dremel (2 speed, mind you)

Well, The short story is that I woke up this morning when a heavy box unceremoniously thumped my head... This shocking thump turned into a wonderful gift, a brand new Dremel 4000 model, with all the trimmings, and a ton of varying sizes of metal grinding heads...

JOY!!

That being said, I was wondering if anyone who works blades in this manner could give me some tips... I'm doing fine at grinding blade tangs into thumbnotches (although, I'm still only practicing on junk razors) but having more difficulty on the regrinding tips...

I have succeeded in making a round point into a square point by simply slicing the tip off (with frequent quenching) using a cutting disk, and then rounding off the spine on my greaseless compound... However, I tried to create a barber's notch in that (remember, junk blade) and blew the temper very swiftly... Also, I've toyed with trying to create an oblique/french point, but have no clue how to create that shape... Cutting disks are too fragile and would chip if they weren't going in a perfectly straight line, and I fear that my metal sanding bits would blow the temper on thin blade metal...

Anyone have advice on dremel tip styles and wielding techniques for reshaping a razor's point?

Thanks,
Jeremy
