Use a cutting board if you may.
Can you use a knife on granite countertops.
Really you wouldn t have to worry about cutting on your granite countertop unless you were using a knife made out of granite.
A gemstone such as topaz will scratch just about anything including quartz countertops but you can t use a wedge made of calcite to this effect.
Don t use knives directly on the granite.
Therefore while you can safely cut directly on a granite surface unless you wish to continuously replace your knife it is advisable to make use of a cutting board.
So to answer the question.
A quick chop here and there will not necessarily wear out your granite countertops.
The granite is tough and can handle the knives.
Yes you can directly cut food on quartz countertops since they can resist any scratching or slicing damage that is inflicted on their surface.
However you can only do this up to a certain extent.
The answer is it depends and it s still better to use a cutting board.
It s your knives that will be sorry you didn t use a cutting board.
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.
If you let a spill sit it can etch the seal and stain the granite.
Just because you can doesn t mean you should.
However if you cut acidic foods like citrus fruits the acid can degrade the surface of the countertop leaving a noticeable dull spot.
