Duosharp Whetstones [Posted on 2006-07-03]
This fine/extra fine whetstone is all that it promises & more. I bought it because of it's large size to accomodate my kitchen knife collection. This whetstone gives me a razor's edge, but I would suggest it's use with a couple of other products:
1. The duosharp coarse/extra course whetstone
2. The DMT whetstone duobase to hold the whetstone securely during use
3. A mousetrap hone, because sharpening is NOT the same as honing.
Great stone [Posted on 2006-07-07]
I researched quite a bit before buying a stone & a steel and I am glad I did.
Oil Stones? forget em they are messy and not nearly as good as the Japanese water stones they wear down and they are slow.
Have a hardness of around 6.5-7 on the Mohs scale and on good knives that have a Rockwell hardness 56-60 and up to 66 they just dont cut it.
Water stones? these are good do a fine job, need to be soaked in water for a few mins, no mess but a good quality Japanese water stone will cost just as much if not more as this diamond stone and most are single grit, they also wear down rather quickly and become useless until you flatten them back out and what do you flatten them with? A big Diamond stone! or Aluminum oxide sand paper like maybe 120-220 grit glued to a piece of glass, which BTW makes a fairly decent sharpening stone on its own (in finer grits 800-2000) that are better than the oil stones.
These are made of Aluminum Oxide in a resin bond, aluminum oxide has a hardness of 9.2 (Mohs) these work better on good knives. These also need to be dried before storing them or they will deteriorate much quicker.
Ceramic Stones? These are good, dont need to be soaked and wont wear out as fast as regular water stones as they are in a "ceramic bond" instead of resin, these are either aluminum oxide or silicon carbide, the carbide is slightly harder at 9.5
These stones will still wear down just not as fast as the regular resin bond water stones.
Both resin bond and ceramic water stones rarely if ever come larger than 8X3" (I have yet to see one, if they exist they would be even more expensive).
This is the only non-diamond stone I would recommend and even then just for a super fine 5000-8000 grit to hone & polish the blade.
Diamond stones? Well this is the only way to go as far as im concerned, no mess at all and if you use water on it the water fills in the pockets and the blade just glides over the stone and stays constantly lubed and cleaned.
These stones cut faster than any other stone have a hardness of 10 (Mohs) and stay flat these are perfect for good steel knives especially the 60-66 (Rockwell) hardness.
The 2 best features of these stones are they stay flat and they are 10X4" which you just cant beat, it gives you nice long easy strokes.
Properly taken care of by the average home kitchen user just sharpening his/her small quiver of knives and in between using a fine steel this stone should last decades.
Using a fine steel everytime you use your knife you should only need to use your stone just a few times a year.
I would suggest this stone DMT 4"X10" Extra Fine & Fine with the Duobase holder which makes it easier to use, then a fine steel like the "F. Dick 11" Multicut Sharpening Steel" which I got here at Amazon also, using this steel makes a HUGE difference and keeps my knife razor sharp.
If you want the perfect polished razor sharp edge also get a Global Ceramic Whetstone, Fine Grit (5000grit) then finish it off with a "Leather Strop" glued to a wooden paddle with a bit of very fine metal polish like white jewelers rouge or flitz and you will have a truly razor sharp and long lasting edge.
Fast cutting, very nice stone [Posted on 2007-08-29]
Not much to say about a sharpening stone except that this is one of those tools that you don't want to scrimp on. The DMT is well made and makes short work of chisels and plane blades, if I ever had to buy another stone, this would be it. Don't forget the coarse/extra coarse stone, they complement each other.
I recomend this stone [Posted on 2008-09-18]
the large size is great, makes it much easier to sharpen longer / wider knives, but also works great for average sheath knives, I use it with and without the stand, both work well.
Gotta love it [Posted on 2008-10-22]
You have to love it when you invest in one item that you randomly pick, and it turns out to be the last one you will ever need to buy.
I did a bit of research prior to buying - and it turned out to be the best purchase for the kitchen, after the food processor.
Now - some five plus years later - it still works like a charm, and all of my expensive knives are in topnotch conditions, thanks to this sharpening stone!
