A steeper bevel (e.g., 35-45 levels) is employed for carving and detailed work, whereas a shallower bevel (e.g., 15-20 levels) is good for heavy-duty functions similar to mortising. As soon as the specified angle is decided, you may proceed with the sharpening course of utilizing a whetstone or grinder.

Refining the Edge:

As soon as the bevel is established, the following step is to refine the sting. This includes honing the innovative to create a pointy and burr-free floor.
