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.
Can you use a knife on granite countertops. The granite is tough and can handle the knives. Hard stone countertops like granite and quartz can withstand knife work in the kitchen without scratching. 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. Really you wouldn t have to worry about cutting on your granite countertop unless you were using a knife made out of granite.
Just because you can doesn t mean you should. Slicing knives across granite to cut food will quickly dull and damage their blades. Don t use knives directly on the granite. So to answer the question.
A quick chop here and there will not necessarily wear out your granite countertops. 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. However you can only do this up to a certain extent. 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.
The answer is it depends and it s still better to use a cutting board. However if you cut acidic foods like citrus fruits the acid can degrade the surface of the countertop leaving a noticeable dull spot. It s your knives that will be sorry you didn t use a cutting board.
