Thread: White Corundum 1k-8K

I found this eBay deal for a set of 3 stones: 1K/4K, 2K/5K, AND 3K/8K White Corundum stones. For the three stones (7" x 2.4" x 1.1") the total is 20$.

Shipping is free. I know you often get what you pay for, so I hesitate a bit to purchase these. But saving $50 plus dollars on these over a Norton is appealing too....

Feedback anyone?

Here is the link for anyone interested:

Knife Grit Sharpener Sharpening Water Stone Dual Whetstone 3000 8000 1000 4000 | eBay

That type of stone was my first synthetic stone. I got a 3/8K.

They can make a shave ready edge but I hated them. I found the grits on the stone close but the 8k wasn't an 8k. The feedback wasn't great.


I'd say spend the extra money now so you don't have to later on when you realize you got a good knife stone. You do get what you pay for with these Chinese made water stones. A block of crap. Either way you'll do what you gotta do. I just wouldn't recommend these for razors.

I thought I'd save a few bucks like you but ended up spending more to upgrade when I realized I was stuck a crappy stone.

I checked your link it's $20 each stone.. Do they even look good to you other then the price?

The seller does not name the manufacturer. So it is hard to look up any reviews of the stones. They are a bit on the smallish side but might work.

The biggest problem is their composition is unknown, they say they are for knife grinding and create a lot of “mud”. As said you may find yourself up grading from these stones rather quickly.

When buying stones for razor honing there are several things that go into a stone that works for a razor, it is not just about the grit size. The binder is most important, most inexpensive stone use a very soft binder to refresh and cut quickly for knives and tools, but a soft binder can be aggressive, messy and become dished or uneven very quickly. The thick aggressive mud can scratch a polished blade and aggressive shaped grits can cause chipping at finishing.

All the modern synthetic stones we use were not designed for straight razors, they are for other sharpening uses, but will work on razors. Of the hundreds, possibly thousands of stones out there, only a handful are proven performers for razor use, stick with those brands and models if you want to learn to hone. Larger stones are easier to learn on, full 8X3 in stones.

King makes the best inexpensive stones, even they are smaller and can be soft, but they work without issue. The king 1k is about $20.

A dual grit stone is also a good buy the Norton 4/8 is a proven performer, as is the 3/8 Naniwa. With a king and a combo stone at less than a hundred dollars, you would be set for life, for honing that is…

great information. Thanks Euclid

There is a good deal on a Norton 4/8 in the Classifieds right now. It has a cosmetic issue but won't affect its function.
