The Scraper Blade's cutting edge is formed by one step on the grinder. The grinding action forms the hook.
Whilst using this tool, hone often with a diamond file.
||The Tormek SVD-186 or SVD-185 is easily used for this activity. As shown in the picture above, you will use the shaft rather than the tool holder.
Reference the Tormek handbook, Water Cooled Sharpening of Edge Tools if you have any questions.
Notes & Comments
If grinding this on a high speed grinder or sander, be sure to manage the temperature so that the temper is not lost due to overheating.
|High Carbon Steel
||Temperature control is critical for high carbon steel. Tempering will be lost in the steel if heated until it is blue (~550°F / 300°C). Cool by dipping as needed in water.
|High Speed Steel
||Cool by dipping as needed in water.
|Steel with Carbide Insert
||DO NOT cool by dipping in water. This will cause the carbide to crack due to shocks.
It is also recommended to use a high grit wheel for sharpening carbide as lower grits can cause cracks in the edge leading to it being far more crack-ridden and brittle. (Lower grits can be used for shaping the edge -- see also, Grindstones and Other Sharpening Media - Quick Selection Guide.)

- Tormek Live Sharpening Class - Part 9 - Sharpen a flat bevel with Tormek MB-100 on a diamond wheel (YouTube video). In this episode we learn how to use the Tormek MB-100 Multi Base to sharpen a completely flat bevel ▼, on the side of Tormek's diamond wheels DC-250, DF-250 and DE-250. For some tools, such as 🎻 luthier knives,🔪 Kiridashi knives, v-tools, chip carving knives and Japanese plane irons, a completely flat surface on the bevel is preferred over a slightly concave, which you get when you sharpen on the rounded part of the grinding wheel. For some people this is more of a personal preference.
Regardless of what might be the reason to want a flat bevel, Sèbastian and Wolfgang show how to achieve it with your Tormek wet sharpening system, They will also touch upon the differences between the different types of bevels.
