Question: Where does it made, how is it compare with those made in China?
Document: I did look, but could not find any info as to where they were made, until I got it in and read the box. Other then that, this is a good product.In the end, yes it is a good product. Yes it is worth purchasing. But, if you are like me and get tired of everything being made in china and want something not made in china, then look elsewhere, which I will do in the future.
I do wish this was a little longer though, as my Kotobuki King one was about an inch longer, which may seem minor, but it can make a bit of difference when using it. This one is about a quarter of an inch wider though. Also the markings on the side so you know which grit each side is, is nice. The one bad thing that I can say about it, is that it is made in china.
I have only used the 3000 side so far, and so far, it works fine. It does not seem to wear down fast, so it looks like it will work for a long time to come. I usually buy Kotobuki King brand ones, and have had very good luck with them. I would say that this one is about as well made as the ones I usually buy.
cuts clean and fast, silicone base was more useful than i expected, there was no damage to the water stone
This is a great quality stone. It's wide and long which makes sharpening longer knives easy. The stone was perfectly flat when I received it. I recommend this over the $80 branded stones by knife makers.A note about the grit. 1000/3000 is a good combination for kitchen knives. You can get a finer edge with say 6k-8k, but that fine edge will dull more quickly. 3000 is adequate enough for a safely sharp blade that keeps it's edge for much longer.
This came in pristine condition and has just been a pleasure to use. Sure, its more tedious to setup, what with the soaking and such but the results are phenomenal.
The stone is approximately 7&#34; long and 2 1/4 &#34; wide. The small black rubber bottom keeps the stones from sliding. If you already have course sharping stones this 1000/3000 grit stone will be very helpful in getting your knifes a lot sharper.
PERFECT SIZE FOR SMALLER  BLADE KITCHEN KNIVES AND WITH PRACTICE LARGER KITCHEN KNIVES ALSO. IT TAKES A SHORT TIME FOR THE STONE TO SATURATE.
My chef knives are pretty sharp, but I did feel it was kind of pricey. Placing a towel or rag at the bottom of the sharpening stone is better than the rubber spacer it comes with.
Loved this honing stone. Bought a straight razor and this stone got it to shaving sharpness. It does a great job and I'd buy from Mercer again.
Answer: I don't know where it is made, but it does a very nice job. I use it to sharpen my straight razor and am happy with it.
