I've been using a Dremel for years and still don't have all of the attachments.
Here is the best to start with IMO:
Variable speed corded (2 if you plan to buy a lot of accessories and really get involved)
Workbench hanging unit (for hanging the dremel upside down)
Flexible Dremel extension
As many bits as you can afford, I made a stand recently to hold all of my bits and I had to drill almost 200 holes, many are duplicates but you'll use them all at some point.
A box to hold all of the sanding, grinding and buffing wheels you'll aquire.
Cool things to get also;
Dremel Vise, cool little attachment to clamp your Dremel in so that you can use both hands to work. Pivots up and down and 360 deg.
Dremel Router (Great for G-10)
Dremel Drill Press
Did I say a spare dremel?
Have fun but I would recomend practicing a bit before tearing into a good knife. I recently butchered a good one by tinkering too much, and I've been doing this as an avid hobbyist for years.
I once read in a gun magazine where a very popular gun smith said "The worst thing to happen to the gun industry was the invention of the Dremel tool" applies to knives as well. I have seen many guns at a show since reading that quote that showed obvious signs of a visit to the dremel butcher.
Here are a couple I did with the Dremel, not REKAT's but all I have ready to post right now.
Have fun and wear goggles or glasses
