Rather than spending big money for some of the new negative rake scrapers, would it be almost as good to grind a second angle on a traditional scraper? If so, what angle should the second grind be?
That works fine. It will take some time to do but worth the effort. The bevels don’t have to be even in length, which will save you some time. Personally I use 35 degrees on both bevels. Some people use different bevel angles which is madness to me.Rather than spending big money for some of the new negative rake scrapers, would it be almost as good to grind a second angle on a traditional scraper?

Me too richard. I use 35 degrees on both sides. I like being able to simply flip the tool over, grind off the old burr, flip and and put a new burr on.That works fine.

Isn't that the definition of a skew? Same angles coming to a line.I put 40 deg on both sides and like others I just flip it over from time to time to keep the edge balanced to the middle. I buy HSS blanks online, a lot cheaper than buying a pre ground tool, and grind the shape I want. You can get various widths and thicknesses depending on what you want. Some I put in sliding pocket sleeve handles and put a different grind on each end. Some I just use without a handle.
The difference between a skew and a nrs can just be presentation angle. Skews make great scrapers, used properlyIsn't that the definition of a skew? Same angles coming to a line.
