Probably the reason you chose granite over other countertop options is that you’ve heard from some reliable sources that it’s a very tough material. While this is true, you still need to know how hard it is so that you will also have an idea of its limitations. 

Granite is not invincible, and if you put too much pressure on its surface using a tool that’s more than its toughness can bear, this naturally formed stone might break off. Granite is hard, yet its hardness can be its weakness. The crystalline structure forming every block makes granite so vulnerable to strong impact. However, since you’re not expected to use your granite countertop for any other purpose than for preparing food, you won’t see cracks or chips on its surface anytime soon. 

 The previous problem with granite, and practically all other countertop materials, is that its surface tends to form tiny pits. Thanks to today’s polishing technology, you can prevent this from happening. Most granite countertop manufacturers apply a thin, mirror-like finish that protects the surface of the material from dents and scratches and also gives it a stunning glaze. 

One interesting feature of granite is that it doesn’t easily get dented by knives. Unless the knife is made of diamond or any other material harder than granite, you can’t expect it to slash through the countertop so easily. In fact, knives are known to sustain damage from a forceful contact with granite.
