Hi Guys, 
As a professional holster maker, I  usually don't get too jazzed over a fairly simple tool but I know that a lot  of amateurs here will try their luck at making their own holsters and there are  also a lot of other active pro holster makers that read these boards so I  wanted to give props where props are due. 
Chris over at Three Mutts Customs made me a pretty sick custom burnisher.  His site is at http://leatherburnishers.com. 
If anyone has ever burnished an edge of leather, you know what a pain it  can be without the right tool.  I can tell you that for the small price  I paid, this tool will save me boatloads of time. Previously, I was using a really old tool I made myself.  It was out of balance and very difficult to use.  This new burnisher seriously looks  like a piece of furniture - made of hard cocobolo wood and is balanced  flawlessly.  It's so pretty I almost didn't want to foul it up with wax and dye and what not....but I did   
This particular version was custom made for me per my  specs.  I sent Chris a drawing of what I wanted and he made an exact  copy. 
If you are a pro or amateur leather worker and have been working with a jerry rigged burnishing tool, I highly recommend these  guys for edge burnishers.  With Chris doing what he does and the price  he charges, there is absolutely no need to attempt making one yourself -  its just not worth the effort.  This is a real deal tool.  Excellent  craftsmanship and perfectly well balanced on my drill press - not even a bit of a shake or nothing.  They make  them with smaller shanks for Dremels as well as larger shanked burnishers for drill presses.   Mine has a 3/8" or 1/2" shank.  What else can you ask for?
