Wood Carving V-Tool Chisel |
The V Tool's cutting edge is best sharpened in the horizontal position (with the wheel rotating away from the user). This reduces the steel removal rate, and allows for easier sharpening of the edge to the right profile, as it is not too fast.
Guidelines shown below are for the cutting edge angles. Since the entirity of this blade's cutting surface is honed, no secondary / micro bevel is given (as with Bench Chisels).
The angle () is the grind angle for both cutting edges (ground first), and the keel (ground last).
Smaller tools | Tormek SVS-38 or SVS-32 Short Tool Jig may be appropriate. It is used in a similar manner. |
Shorter tools | 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. |
Use the Projection Calculator to set the projection and USB distance from the grindstone. This calculator is web-based and does not require Excel.
If you want to grind a flat bevel on the edge and you are using a Tormek, watch the video below on using the MB-100 Muti Base. The SVD-186R Gouge Jig works well with the MB-100.
The shape of the grind used is a call best made by the tool's use, based on their own experience. Additional notes are available on separate web pages for Grind Profiles, and Micro / Secondary Bevels.
Carving edges are typically not reground. It is usually done only when needed to reshape them, or repair a problem with the edge. More commonly, the edge is simply honed on the leather wheel.
The commentary that starts at 10:40 about setup of the Tormek SVM-00 Small Knife Holder Jig are excellent.
Around 24:00, there is a discussion on sharpening hook knives (with the grind on the outside edge). Sharpening the inside edge must be done by hand, or using the method advocated in The Complete Guide to Sharpening (1996) by Leonard Lee.
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.
