Diamond Sharpening Stones FAQ

Q Are diamond sharpening stones worth it?

A “Diamond Sharpening Stone”
Diamond stones have key advantages over other types of sharpening stones. Diamond stones are the fastest cutting sharpening stones. Speed is especially helpful when working with coarse grits where you may spend additional time on a dull edge.
Q Which diamond stone is best?

A When buying diamond stones, Huayida suggests getting a coarse stone between 120 - 400 grit ( 300 is best ), a fine stone between 600 - 1000 ( 600 is best ) and a super-fine between 1200 -1500 (1200 is best).
Q What is 1000 grit sharpening stone used for?

A Less than 1000 grit is typically used to repair knives with chipped edges, 1000 to 3000 grit are used to sharpen dull knives, 4000 to 8000 grit are finishing stones and are used to refine your knife edge.
Q Can you sharpen a knife with a 1000 grit stone?

A The #1000 grit whetstone is your go-to sharpening stone. If your Japanese knives need a good sharpen to regain their edge, then this grit is your starting point. But use this sparingly as it will wear your knife down.
Q Do you need to flatten a sharpening stone?

A We recommend flattening them at the beginning of every sharpening session-it's a 15-second job in most cases. Flatten oilstones about every 10 sessions. Another benefit of flattening your stones: You'll remove embedded metal filings that impair the stone's sharpening action.
Q Can you over soak a sharpening stone?

A Rough and medium grit whetstones should be soaked in water for 10-15 minutes prior to usage. When using fine stones, simply splash water on the stone as you sharpen. If you soak fine stones in water for too long, they can begin to crack.
Q Which side of the sharpening stone do I use first?

A If your whetstone has a coarse and fine side, begin with the coarse side. The same goes if you have multiple whetstones. Work from coarse to fine.
Q Is oil or water better for sharpening stone?

A Is oil or water better for sharpening stone? Water stones are softer than oil stones. This softer binder promotes faster cutting because the old abrasive material breaks away and is replaced with fresh sharp material. Fast cutting is a clear an advantage of the water stone.
