Guidelines shown below are for Included Angles ().
Green wood carving can have a lower included angle () than dry wood carving.
CB's USB Projection Calculator is recommended for calculating setup for Tormek knife jigs. (The simpler Projection Calculator is also still available.)
|Chip Carving Knife||20°
||Concave or Slightly Convex||Could be as low as to 15° or 16° included angle, especially on softer woods. The Scandi grind can be "grabby" on the wood when slicing into it. The micro-bevel grind does not cut as cleanly.|
|General Carving Knife||20°
||(see below)||Could be up to 25° included angle.|
|Sloyd Knife||22 - 25°
Can go smaller or greater, depending on need. The convex grind is preferred by some as it gives a radius from which to adjust the angle of attack. Others say differently. You will need to identify which you prefer.
Some versions of this knife, more common with those which are hand-made, do not have the same angle on each side. This means the Bevel Angle () may not be 50% of the Included Angle ().
It is advisable to use a Sharpie marker to ensure you are grinding the same angle as was delivered. Once you have achieved the angle that matches the grind, record it onto a label attached to the knife. This will enable you to repeat the grind easier next time.

Tormek Live Sharpening Class - Part 4 - Carving Knife & Carving Tools
Wolfgang and Sèbastian from Tormek go through the sharpening of carving knives and various carving tools such as v-tools, carving gouges and short wood chisels.

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.
