I guess you used a diamond abrasive to polish the carbide but it still must have been difficult. Rob Alexandre,

Thanks for the comment. I guess you used a diamond abrasive to polish the carbide but it still must have been difficult.

Unfortunately, its carbide rod was not polished, just ground. It was leaving tracks on the burr. It took quite an effort to polish it somehow. With steel burnishers, I don't have much luck with modern hard scrapers. Those scrapers even dull Nicholson file at once. The file that LV supplied in the kit, though, works.

It worked well for me and, I agree, it produces a consistent burr along the entire edge. I like a simple handled-rod burnisher which can also be used to "consolidate" the edge prior to forming the hook, can form the burr with the compound stroke that I described in the post, and can form the hook with progressively more angled passes which I think gives a sturdier hook. It's just personal preference really. There are many good ways to do all of this like just about everything else in woodworking.

Have you used it? I have been very satisfied with how it creates a consistent burr on the edges of scrapers. The hardness of the steel I couldn't tell you, and I wonder how important it is. I usually have it set at five degrees, and as long as the edge of the scraper has been prepared well, in three passes, with just slight downward pressure, I get the right burr. Depending on the number of passes and the pressure, it can be lighter or heavier, but what I like is that it is very even over the length of the blade. Best, Tico Hi Rob,

Ask them, but I certainly would trust either of those excellent tool makers to have chosen an appropriate carbide. Happy scraping!

Their web sites don't give this information. And since the folks at Innovative Carbide are not selling these rods other than by special order, what would be be best way to go? I guess the Blue Spruce, it's the prettiest. Wesley Hi Rob

If you want to go deluxe, give carbide a try. The 10s carbide is much harder, Rc 78-80 (Ra 91-92). Rob Hi Wesley,

They say theirs are hardened (Rc64) and polished tool-steel rods that stand up well to constant use on scraper edges. At $15 (sans handle) this seems like the best deal.
