Understanding Japanese Whetstone Grits

I posted a video on this topic, so watch the video if you don’t like reading.

There are three main whetstone categories. 

Fixing: Whetstones with ratings up to 320 grit. These are for fixing chips on blade edges or bringing incredibly dull knives back to life. They are not for weekly use. 

coarse: up to 140 grit are strictly for fixing large chips 

medium 220-240 grit are for micro-chips on a blade edge

fine: 320 grit is for incredibly dull edges or the transition between fixing and sharpening whetstones.

Here are my favorites in this category.

Sharpening: 400 – 3,000 grit – whetstones in this grit range are too inefficient for fixing chips.

Coarse: 400-600 grit whetstones are great for dull knives but too slow for fixing chips

Medium: 800-1,500 grit range is the most critical and is where your knives will get their edges. 

Fine: 2000-3000 grit whetstones are not popular, but if used correctly, they leave your knives with incredible edges without needing to go to a 5k or 6k whetstone. Please read about my favorite 3K whetstone and how I maintain my knives.
