Jende 1x6" Resin Diamond Sharpening Stone for Edge Pro, Hapstone, TSProf, Jende JIGS for Knives (15 Micron (1,000 Grit))

Some of the best resin bonded stones you can buy in performance but the last two seem to have a adhesive problem and was peeling off the blank and had to be returned. I have the entire set that I bought years ago directly from Jende and I have loved them but my 120, 60 and 30um are getting thin after literally thousands of knives sharpened on them and many lappings to resurface them and keep them perfectly flat so they need to be replaced. The 15um and smaller are still good to go for many many more sharpenings and still have probably 65% of the resin layer remaining but my coarser stones do the heavy lifting of course and they wear more due to reprofiling and damage correction so you spend far more time on the coarser stones than the finer ones. These have incredible value for your money at 69 bucks for what is in my professional opinion the best resin diamond stones on the market and I've tried them all and have most other brands but the Jende stones are what I prefer to use when in sharpening on a fixed system and I even use these a lot for stone in hand free hand sharpening as well. The cut speed of the 120um is very fast for a resin bonded stone as they typically don't cut all that fast even the coarser stones like say the well known russian resin stones in F80 grit doesn't cut nearly as fast as the Jende 120. The 120um Jende cuts faster than pretty much any other resin stones I've ever used, they have a very nicely dialed in resin matrix so the feedback is excellent as is the final edge quality. The ease of use of these stones is great because they are lapped nice and flat right out the package. I really wish they wouldn't have been peeling up I really needed the new stones to replace me pretty well worn out ones, idk maybe the heat got to them and was making them peel up? Idk but I went ahead and grabbed them directly from Jende and they was good so I have me a fresh 120, 60 and 30um now so I'm good to go for thousands more knives. My side business has been knife sharpening for about 9 years now, I'm a well known free hand professional that specializes in sharpening super steels be it on kitchen, outdoors fixed blades and folding knives but I also do a lot of fixed angle sharpening as well, ide say I do about 70% of my sharpening free hand and 30% fixed angle, when the customer asks for me to do fixed angle that's what I do but most want my free hand edges. These stones cut steels like M4, s90v, rex76, rex45, s110v, s125v, rex121, hap40, hap72, zdp189 etc etc very very well and leave an absolutely perfect aggressive adn sticky edge profile in the mid grits, the 30 and 15um are excellent mid grit stones for vert sticky sharp edges with a lot of bite/tooth. If your looking for extremely bright mirror polishes Jende resin stones do that amazingly well, some of the best mirror finishes I get come off Jende resin stones, run the progression from whatever the start grit you choose and simply go 15um, 9, 3, 1 micron and you are left with a absolutely brilliant mirror finish with a scratch pattern that isn't visible to the eye then simply strop on some tenth micron diamond or cbn emulsion on kangaroo leather and you will have a flawless mirror finish. The resin they use in these stones works better than most as it leaves such a high level of edge quality, some resin stones leave a beautiful finish but the edge quality isn't great and it just won't be as sharp as it should or the bite will be very low and that's due to the resin it's self in most cases but this resin leaves incredible edge quality with a high level of sharpness and great bite even at the higher grits. If Jende made this set in 3x8 bench stones ide buy the full set on the day they released them as they are THAT GOOD. If your looking for a top performing set of resin bonded diamond stones for fixed angle then look no further than Jende as they are the best. PDT who?? Lol. Venevsky what?? Lol CGSW huh?? LOL.. Jende resin stones are the best hands down, like I said I've used them all and when it comes to resin bonded diamond stones Jende is where it's at. They have the tightest spread of diamond particle sizes of any resin bonded diamond stones I've ever had except for Hap Stanleys stones and they are close to as consistent as his and that's impressive. Most all resin stones even the premium ones have some noticeable grit contamination if you use a microscope to look at the stone but Jende has VERY VERY LITTLE grit contamination and none that is off enough to be meaningful. Like in the 9um stone we messured diamond particles between 10.2um and 8.7um with a 9.3um average that's INCREDIBLE. No other resin stone except for Nano-Hone has anywhere even close to that level of diamond particle size consistency and that's exactly why Jende stones leave such an incredible quality of mirror finish if you take the edge to the 3 or 1um stone. The 1um stone we messured particles under the microscope (a very high end digital scope that cost around 40k dollars and is used to QC lithography on processors so you can messure down to something like 0.006 micron accurately with it) and we found a spread of 0.6um to 1.3um with a average of 1.1um that's unbelievable how tightly that diamond is graded, the mono diamond they use in these stones is of the finest graded quality and they must pay an absolute premium for that diamond to be graded in size that tightly. Mono diamond is very cheap if it's loosely graded with a large particle size range but the tighter the particle size range is for a given micron the more costly it gets and for it to be graded this tightly it's as good as it gets and the diamond has to cost them a premium. F2000 resin diamond stones they are a 0/1 micron stone and when we messured them out the diamond range run between 0.3um and 3.2um with a 1.6um average so that stone is said to have diamond in it between 0um and 1um and we found pieces as big as 3.2um and that is exactly why that 0/1um stone doesn't leave close to as perfect a mirror as the Jende 1um does and it's simply because of the grit contamination. Whoever Jende sources their diamond from really does a great job at grading the diamond sizing as it's absolutely as good as it gets and for these stones to be only 69 dollars when other premium resin stones are up in the 80 dollar or more range and aren't nearly as consistent in particle size as the Jende are that shows you have great a value Jende resin stones really are not to mention the resin matrix in the Jende stones is absolute perfection and better than any other resin stone I've tried and is totally non-abrasive unlike some other resin stones that have boron in the binder/resin causing the resin it's self to be abrasive and leave scratches in the edge bevel that will be a different size than the diamond. I think the resin layer peeling up was a fluke and was from the heat of being left on my porch in the sun all day while I was at work so I'm not going to deduct anything form the rating for that. These are the best resin diamond stones on the market and they fully deserve a 5 out of 5 star rating.

These are some of the most consistent resin bonded stones you can buy. The diamond sizing in these stones is incredibly consistent with little to no grit contamination to speak of as the particle sizes are so close to one another, much better than most other resin stones on the market. The concentration of diamond is very high so these stones, cut very fast and leave a near flawless scratch pattern due to the very consistent diamond sizing. The only complaint I have about this stones is that you only get about 2.2mm of diamond layer and at the price of these stones that's not cool. Premium resin stones in the 70 dollar a stone range will all have 3+mm of abrasive layer buy not these they are a little more 2mm that's not cool. I still think they are some of the best resin stones on the market but it's kinda hard to stomach 2.2mm of abrasive layer on a 70 dollar resin stone so after you lap them perfectly flat out the box you already have under 2mm of stone. For the price of these stones Jende absolutely needs to be giving us 3MM or more. With that said they are my fav resin bonded stones and I've tried pretty much every premium resin stone brand out there. If they made these on 3x8 inch bench stones I would order a full set the day they released them. Yeah they aren't 3mm thick abrasive layer stones and that sucks BUT they are the best resin stones I've found as far as overall edge finish quality goes and that's what matters most and not to mention they use a very hard resin they are slow wearing and require very little lapping so they will last you a very long time but I still wish they gave a full 3mm of resin layer. With that said they are around 15-20 bucks a stone cheaper than other premium resin stones that are 3mm resin layer stones so I guess that factors on to it, I would still rather them give a full 3mm of resin even if they upped the charge to 90 a stone. Performance these are 5 out of 5 stars Value with 2.2mm of resin at 70 is -0.5 star so they get a 4.5 out of 5 star overall rating.

When I purchased my sharpener, it came with a few water stones. My attempts to repair damaged knives and handle the different types of Japanese and German steels of my knives was frustrating and sub-par. That's when I discovered, the stones that came with the system were inadequate for a lot of jobs. Not wanting to break the bank, I looked for a system of stones that would handle all of my knives.. The Jende resin series of diamond stones is just such a system. The initial cost is not cheap, but after multiple uses - these stones have proved their worth. I own 5 of these stones in various grits. You can buy cheaper stones, but in the end, if you are going to sharpen your knives, you will end up buying these stones or ones very much like them.

Almost mirror on blade when finished.

This is my first resin stone. I touched up one little blade with this stone in seconds! For now, it seems like it is going to live up to its price and hype! I will buy several more :)

Not flat ; swaybacked / concave / low in the center and high on the ends . Good for free hand sharpening ; disastrous for jig sharpening . Oh well it is a halffast world.

Great finishing stone to get a decent mirror edge followed by their micro strop.

These resin bonded stones are my current favorite. I’d love to see them in an 8”x3” format.

One of my favorite CBN diamond stones.I used this in my free hand sharpening and it works really well.

Very well made, works perfectly in my tspfof

Unreal quality. I've used cheap stones in the past, and I'll never go back. They are expensive, but when you see the results you get, it's worth it. I can get actual MIRROR finishes on my blades and I can literally SEE myself in them.

Expensive but worth it. I can get insane mirror finishes with these. I've got 3 of these: 15 micron, 9 micron, and 1 micron. They work with pretty much any fixed angle system that takes 6" stones.

Used it after a 4000 grit diamond and this thing left deeper and bigger scratches.
