What is the difference between a coarse and fine grit whetstone?
The grit of a whetstone refers to the size of the abrasive particles used to sharpen the edge of a tool. Coarse grit whetstones have larger particles and are used for repairing damaged or very dull edges, as they can quickly remove metal and restore the edge to a usable state. Fine grit whetstones, on the other hand, have smaller particles and are used for honing and polishing the edge, producing a razor-sharp finish. Coarse grit whetstones typically range from 100 to 400 grit, while fine grit whetstones range from 600 to 1200 grit or more.
Using the right grit whetstone is crucial for achieving the desired level of sharpness. If you start with a fine grit whetstone, you may find that it takes a long time to remove significant amounts of metal, making the sharpening process tedious and time-consuming.
