improved quality and price
Getting to like it more over time. Previous stones blistered and shed their nickel matix in places leaving holes which led to blades catching and ripping even more out. So far this seems to be an improvement. Price is certainly more competitive than prevously.

Jag är nöjd med denna slipsten, den är stor och ordentlig. Jag använder den till mina slöjdverktyg och köksknivar med bra resultat. Ska tillägga att detta var den andra stenen jag fick för den första var defekt med "blåsor" i ytskiktet så det trillade av när jag använde den. Men denna är som den ska.

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.

Beim Messer schärfen habe ich schon so allerlei ausprobiert und bin am Ende bei DMT und dem blauen und gelben Brocken hängen geblieben. Der 10" DuoSharp Schärfsten extrafein und fein von DMT zu Beginn des Schärfens und danach noch einige Male über den blauen Brocken und zu guter letzt noch ganz sanft über den gelben Brocken stellt für mich das non plus ultra dar.
