Friability
When you're looking for the perfect grinding grit, one of the things you need to consider is friability. This is a measure of how quickly the abrasive material breaks down under use.
If you're looking for a fast sharpening speed, then you'll want to choose a grit with a low friability. However, if you're looking for a high-quality finish, then you'll want to choose a grit with a high friability.

It's important to find the perfect balance between quality and price when you're choosing your grit. You don't want to spend too much money on a grit that's not going to give you the results you're looking for.
Resistance to Loading
The grinding grit resistance to loading measure of how quickly the abrasive material breaks down under use.
If you're looking for a fast sharpening speed, then you'll want to choose a grit with a low resistance to loading. However, if you're looking for a high-quality finish, then you'll want to choose a grit with a high resistance to loading.
Operating Temperature
Generally, the higher the operating temperature of a grinding grit, the faster the sharpening speed. However, you also need to consider the maximum temperature that the abrasive material can withstand.
You don't want to choose a grit that's going to break down under use, so be sure to find one with a high operating temperature.
Size and Shape of Abrasive Particles.
When you're choosing a grinding grit, be sure to consider the size of the abrasive particles. The smaller the particle size, the finer the finish will be. However, if you're looking for a fast sharpening speed, then you'll want to choose a grit with larger particles.
Tips for Keeping Your Knives Sharp

- Use a honing rod or strop to keep your knives sharp between uses.

How to Tell if Your Knives Are Sharp Enough?

- First, try slicing through a piece of paper. If the knife cuts cleanly and effortlessly, then it's sharp enough.
- Another test is to try chopping a vegetable like an onion. If the knife slips or tears the onion, then it's not sharp enough.
- Finally, you can try shaving a piece of hair off your arm. If the knife pulls or tugs at the hair, then it needs to be sharper.
