It s your knives that will be sorry you didn t use a cutting board.
Can you use a knife on granite countertops.

Yes you can directly cut food on quartz countertops since they can resist any scratching or slicing damage that is inflicted on their surface.
The granite is tough and can handle the knives.
Since knives are not typically made of granite or any other mineral you could purchase a granite countertop color and feasibly not purchase another cutting board as long as you have your kitchen.
The answer is it depends and it s still better to use a cutting board.
Slicing knives across granite to cut food will quickly dull and damage their blades.

Really you wouldn t have to worry about cutting on your granite countertop unless you were using a knife made out of granite.
However you can only do this up to a certain extent.
Quite a few stainless steel knives rank around 7 on the mohs scale thereby enabling them to scratch quartz countertops which also rank around 7.
