Guidelines shown below are for Included Angles ().
Notes are also available on a different web page for Micro / Secondary Bevels.
Many marking knives, especially Japanese marking knives are sharpened only one side. For those,
CB's USB Projection Calculator is recommended for calculating setup for Tormek knife jigs. (The simpler Projection Calculator is also still available.)
Included angle is the same as the bevel angle as only one side is beveled. The back is flat, and it is fundamentally sharpened as if it were a woodworking chisel.
Generally, there is a 120° angle on the leading V. Some chose to round off the pointed tip.
The Tormek SVM-45 works well for these.

Wolfgang and Sèbastian from Tormek talk about different techniques for knife sharpening.
Tormek Live Sharpening Class - Part 9 - Sharpen a flat bevel with Tormek MB-100 on a diamond wheel
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.
