Although some chisels can be sharpened with any kind of sharpening stone, some have specific needs and can be sharpened with only a particular sharpening stone. In this article, we have covered the various types of sharpening stones alongside what kinds of chisels you can sharpen with them.
3 Types of Stones
Water stones are the sharpest stones and come with a wide range of grits. These stones are typically made of aluminum oxide abrasives that make them more convenient and easier to use. Although oil stones are also made of this material, water stones are more reliable and sharper in nature. Firstly, they require water for clean up in spite of oil which makes it inexpensive. Secondly, the binding material that holds the stone together is softer in nature which helps to sharpen the tools faster than oil stones making it the best choice for woodworking tools. 
Since water stones come in a wide variety of grits, specifically coarse grits, you can sharpen almost all kinds of chisels and planes with this stone. However, it would be best to avoid the sharpening of heavy-duty chisels on water stones due to their softness.
