TormekSVS-38 Short Tool Jig or SVS-32 may be appropriate. It is used in a similar manner.
You may need to use a standard, off-the-shelf collar to guide the sharpening process. Most hardware stores carry these, or you can order one such as part number 9414T9 (7/16 inch) or 57485K68 (10 mm) from McMaster-Carr. Note : You will probably need to replace the set screw with a longer one.
When sharpening, be very careful about the edge's shape. But be cautious about taking a decision to round the corners off too fast. It is easy to do, but often requires quite a bit of grinding and metal removal to re-establish a flat edge profile.
The diagrams below show the edge when viewed from above.
A flat edge with crisp corners (i.e., a straight line when viewed from above) is needed for operations like lettering.
A slightly rounded edge works well for work such as sideways slicing.
Hollowing and leaving no tool marks are best achieved using a tool which has its corners a bit "softened".
The inside surfaces of bent and spoon gouges (shown in red below) need particular care. The surface should have a smooth, flowing shape to allow the removed wood a smooth transition away from the surface. If not, it can cause tears in the surface.
Rounded cutting bevel
Smooth inside surface
The bevel on the gouge needs to be convex when cutting into curved wood surfaces, and this bevel's radius needs to be smaller than the hole. Doing so reduces the bruising to the wood as the carver rotates the tool through the cut.
This is shown in the area marked red in the picture to the right..
Microbevel on inside surface
One school of thought is to put a secondary / micro-bevel on the inside of the gouge's curve. The thinking is that this allows the shape to be longer, more tapered, but not have too acute an edge angle as to be less usable on harder woods.
This approach also allows the tool to be held at a shallower angle (to the wood) which makes carving easier.
As shown to the right, this can increase the effective cutting angle by 2° - 5° quite easily, without having to regrind the larger surface.
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.
At about 45:00, there is a good discussion about sharpening bent gouges, and setup of the SVD-186 jig.
At about 50:00, there is a good discussion about sharpening back bent and spoon gouges, and setup of the SVD-186 jig.
