Reddit mentions of Suehiro Kitchen Both Sides Whetstone # 3000/# 1000 Skg-24 (Japan Import)

>• Splash and Go vs. Stones that require soaking

A matter of taste, mostly. Splash and go means that you can apply water to the surface of the stone and begin sharpening immediately, soakers need to be soaked for a few minutes (half an hour at most). Some soaking stones need to be dried carefully or they may crack. If you don't have a lot of storage or counter space, splash and go will be more convenient.

>• Synthetic Stone vs. Natural Stone

For a first stone, you only need to look at synthetics. Natural stones are inferior to synthetics in the coarse and medium grits. Arkansas stones can make for good finishers. Japanese naturals are expensive and esoteric.

>• Fine Grain vs. Coarse Grain

Fine stones have smaller abrasive particles, coarse stones have larger ones. Fine stones tend to be denser and less porous. Coarse stones tend to cut faster, but it can be difficult to form a sharp edge using a coarse stone alone, thus the popularity of 2-grit combination stones. Most people start sharpening on a medium grit (~400-1200 grit) and finish on a fine grit (~3000-8000). The coarsest stones (80-300 grit) are mostly reserved for repairing damage to the edge and grinding large sections of the blade. Different stones, even those with the same grit rating, may grind at different rates and produce different finishes due to differences in the way they were manufactured (type of abrasive, type of binder, heat, pressure, scale used for grading, etc.).

>• Wooden Base vs. No Base

Again, personal preference. If the stones are to be kept permanently soaked, stones without bases are preferable. The stone with which this comes up the most is the Suehiro Rika, which many people prefer to keep soaked.

>What makes a quality whetstone?

Uniformity of scratch pattern, resistance to clogging, resistance to dishing (becoming concave), rate of grinding, auditory and tactile feedback. Dense stones are almost universally preferred, but it's difficult to generalize beyond that.

>What should influence my decision to purchase one over the other?

Budget, availability, the types of knives being sharpened. Knowing your boyfriend's temperament. Is he patient? Is he careful with his knives? Does he drop things all the time?


I use a King Deluxe 300 and a Shapton Ha no Kuromaku 2000 for most of my sharpening. Both are splash-and-go and very dense ("hard"). I have a dozen or so other stones that I don't use nearly as often.

Suehiro's vitrified stones are among the most user-friendly and least fussy. Almost all of them need soaking. The SKG-24 is a good combination stone on which to learn.

Naniwa makes a huge variety of stones, most of which are good. Their QA-0124 is a splash-and-go stone, although the fine side works better after a brief soak, and even then it dries out quickly. These stones can crack if soaked and then dried unevenly.

King KW-65P is a good, traditional soaking stone. It goes out of flat more easily than some of the newer types of stones but it's a nice size and easy to maintain. The KDS is also widely liked.

Imanishi/Bester can be all over the map. I like their Arashiyama, Latte, and Tamago stones but not so much the Besters. They make a lot of stones that are resold under other brand names. I suspect they're behind this combination stone, which I like—splash-and-go and wears slowly.

All the above applies to Japanese "waterstones" (I don't like that term). "Oilstones" (I also don't like that term) like the illustrious Norton India can also provide good results, and are less demanding in terms of maintenance (flattening, drying, etc.). There are also diamond plates—I like EZE-LAP and ATOMA the best.

Edit: Fixed links.

You should really link the products you're talking about here.

I still have to ask who you are trying to convince. FWIW, I don't recommend the King KW-65 1k/6k but the kind of person you argument would apply to is the kind of person who wouldn't by the KW-65 anyways.

The stone in question is $28 on amazon: https://www.amazon.com/d/Sharpening-Stones/KING-KW65-Combination-Whetstone-Plastic/B001DT1X9O. That's half the reason it's recommended. The other half is that the "King" brand has many better and more expensive popular products and as such it's sort of like a household name among sharpeners and so people trust brand. Everything you are arguing for could be completely correct, but it doesn't matter because there is still a "cheapest option" be offered by King; being offered by that household brand people trust.

I usually recommend this Suehiro instead of the King since it's similarly priced and arguably better: https://www.amazon.com/Suehiro-Kitchen-Sides-Whetstone-Skg-24/dp/B000OZ6XMU

But none of that matters until it gets traction as a household name around here.

edit: For clarification, the reason I'm playing devil's advocate here is because based on your argument you seem to think that people are recommending the King out of malice or just plain ignorance. The former is most certainly never the case and the latter I think happens less than you might think.
