How to use skew chisel?
Oct 11, 2021 · The skew chisel works on planning cuts, V-cuts, and forming beads. Bevel angles vary from 25° to 45°. A 25° bevel angle gives you a fragile edge that needs regular sharpening. Yet, it gives better results. A 45° bevel holds up well in tough stock, but it does not cut easily.

Is there "best" angle for chisels?
You want to create a flattened edge at roughly a 30-degree angle to the tool’s sides. Check your progress by eye or, for greater accuracy, gauge the angle you’ve created with a 30-60-90 drafting triangle. I also use the belt sander to simultaneously grind and round the 15-degree bevel on each side of the skew chisel.

Yet, it gives better results. A 45° bevel holds up well in tough stock, but it does not cut easily. A good rule of thumb is to make the bevel length about 11⁄2 times the tool thickness.
How to sharpen a chisel with sandpaper?
Attach sandpaper to a glass surface using a strong adhesive. Since sandpaper has a course surface, it is effective in sharpening the edges of wooden chisels. The glass comes with a smooth and flat surface that holds the sandpaper as you work.

Does green wood dull blades?
Hardwoods dull a blade faster than softwoods do. The moisture in green wood makes it easier to cut than kiln-dried wood and extends the life of a cutting edge. Knots, twisted grain, or other defects in the wood increase the frequency of the need for sharpening your skew chisel. And, of course, any dirt on the wood makes the blade work harder and means that it will need more frequent sharpening.
How to sharpen a curved tool?
Now for the curved section. You’ll grind and sharpen this in one long sweeping motion, using your fingers as a pivot point (Photo 5). Start next to the straight section, then rotate the long point off of the wheel. Continue in one fluid motion down to the short point. Stop when the area around the short point is square to the wheel (Photo 6). Then, without changing your hand position, rotate the tool in the opposite direction, back toward the straight section. The idea is to fan the tool back and forth without lifting it from the tool rest. Make three or four passes on one side of the tool. Then flip the tool and make an equal number of passes on the other side. Continue sharpening and flipping until the bevels meet at the cutting edge.
How to modify a conventional skew?

How many degrees should be between bevels?
The length of the bevel should be approximately 1-1/2 times the tool’s thickness. The angle between both bevels will then be 35 to 40 degrees. As you grind, you’ll probably have to tweak the tool rest’s angle to get it right. Begin sharpening the straight section (Photo 3).
