Scraper Blade  

Edge Angle

The Scraper Blade's cutting edge is formed by one step on the grinder. The grinding action forms the hook.

Sharpening the blade using the Tormek SVD-186


Whilst using this tool, you may need to hone often with a diamond file.

Crafts make us feel rooted, give us a sense of belonging and connect us with our history. Our ancestors used to create these crafts out of necessity, and now we do them for fun, to make money and to express ourselves.

65° 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

Information regarding Grindstones

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.)
