Well, due to the shut down of every thing, I have been working on video scripts, including one on the NRS. For a burnished burr, I tried the standard round card scraper rod, and I had trouble getting a burr on M2. With the triangle burnishing tool, I could raise a burr. I have long since switched to M42 and V10 tools. I don't think it is possible to raise a burr on them with the standard burnishing rods. You need a material that is harder than the metal you are trying to raise the burr on. This would be micro grained carbide. This would be old router bits, or some reconditioned solid carbide bits, and probably a few other options.
I prefer the burnished burr to the grinder burrs or the honed burrs. They just last longer. Most of the time I don't bother to hone off the grinder burr, and use that burr till it is gone, burnish it down, which usually breaks it off, and then burnish a new one up. You can hone the grinder burr off first if you are being really picky, and that can be necessary some times. I haven't experimented a lot with a honed burr, but I would think they would out last the grinder burrs, perhaps more so if you use a finer hone. For the grinder burrs, I raise then in standard method, sharpen the top bevel, then raise the burr by sharpening the bottom bevel. Some prefer and claim that the upside down burr is sharper, which means that when you raise the bottom side burr, you have the grinder platform at a negative 60 or 70 degrees, or there about... As for the veritas burnishing tool, it is made to be screwed down to the bench top and you use a pivot point. The angles of the rods are intended for scrapers with about a 70 degree bevel. I would think that hand held would be better. Depending on your angles, it may take more or less pressure to raise the burr. It really takes very little pressure to raise the burr.
I am curious as to what angles you are using. Are your NRSs like the skew chisel, in the 30/30 range, or more like the standard scrapers in the 70/30 range? I have settled on 60/30 for my angles. The more blunt bottom angle leaves more metal to support the burr...
