The Robust Large Negative Rake Scraper is made from Hardened and Nitrided M2 tool steel and measures 1” across and 5/16 thick. The bottom edges are radiused so that you can use it at an angle for even more effective cutting. The tang is rectangular, but will fit the 5/8″ handle adapter.
It is shipped sharp. Sharpening just the bottom bevel maintains the nitriding on the top edge. Over time, you may eventually remove the top bevel and need to regrind it to maintain the negative rake. Just remember, there is heat treated M42 HSS under the nitriding, so you will still have a superior tool. The tang is rectangular, but will fit the 5/8″ handle system.
