break.


Here is a link to Diefenbacher Tools' site. They offer three types of 
burnishers for scrapers - round, oval and (yes) triangular - and give 
some insight into their use.

You read it there first.


I did manage to find the 3-corner blank file I picked up from LV - 2 of 
them, actually. They were shaped and roughly belt-sanded lengthwise to 
sharp-ish corners, but are not usable as either a scraper or burnisher 
as is, so I'm unable to report on testing as burnisher just yet. Made by 
Blu-Dan of Austria, a maker primarily of files and rasps it seems.  
Here's a link to their site:

Blu Dan is a name I haven't noticed before this. Does anyone have 
experience with the quality of their products?
