Spyderco CBN Benchstone Double Sided Sharpener Cubic Boron Nitride

Product Information

CBN sounds like a wonderful abrasive that is far better than anything else on the market. So what’s the catch? The problem with them being soldered in place is that when you are sharpening the diamond's are so hard they dig and hook into the steel and get torn out when you sharpen and then you do not have many diamonds left on the diamond stone.Where as with Metallic Bonding the CBN stone's I have the CBN particle's are better anchored in and are much harder to tear out. Metallic CBN stones may have tone imperfections. Metallic CBN may become darker over time due to natural metal oxidizing, it does not affect the sharpening.

Please note, images shown on Spyderco.com may be of Production Prototypes. Modification of products, materials, measurements, technical specifications and availability can occur. If you reverse those two categories of stone for each role (shaping vs sharpening), you have made your job much more complicated and involved and in general it will take you much longer and/or require elaborate deburring steps. With something like a simple Naniwa Multistone 1000 : one can literally grind all day with a creamy slurry created by just a few passes of a flattening plate like an Atoma and NEVER actually reach a strong burr or sharp apex. Technically speaking it is a little more complicated than what we just described. First of all there are two different types of natural sharpening stones, second of all ceramic and diamond-coated sharpening stones are both synthetic sharpening stones. There are, however, so many differences to mention when it comes to natural sharpening stones, ceramic sharpening stones and diamond-coated sharpening stones. Let's start with the natural sharpening stones: Natural sharpening stones CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones. I also got 2 Ruby Red stones that they sell from China because Michael Christy mentioned in a youtube video he really liked the Ruby Red stone and although he did not say it came from Gritomatic he use's the Venev stones so I'm going to guess the Ruby Red he use's is the same one they sell and that's where he got it from.Woodcarving Carving Sets Full Size Carving Tools Sculpture Tools Palm Carving Tools Carving Knives Carving Accessories Power Carving Tools Burrs & Accessories Some threads at Spyderco forums are relevant to this discussion. It wasn't talking specifically about super steels as the OP is, but the question was how to incorp the diamond/cbn rods into your sharpening strategy. Linked below are several threads that have interesting info about all this, including comments from Sal Glesser, Cliff Stamp, and others. And Cliff's testing results on CBN. Lot of interesting info in there, for folks trying to understand the various options that you have on Sharpmaker, and how to get the most out of your Sharpmaker. In addition to the above mentioned ceramic sharpening stones there are also ceramic sharpening stones to which extra sharpening particles were added. Comparable to the garnets in a natural stone these sharpening particles are extra hard and often made from synthetic sapphire. Also known from the watch glass in more expensive watches. Examples of these types of stones are the sharpening stones made by Spyderco and Fällkniven. Diamond-coated sharpening stones There are many different types and sizes of sharpening stones. In this topic we discuss what materials are used to produce sharpening stones and what the (dis)advantages of these materials are. As such you can decide which material will suit you best. Let's start with the short version. Are you interested? If so continue reading to find out more in the extended version! In a nutshell: I honestly don't think it will matter either way when your talking about diamond or CBN,I think the problem is most people still refer to diamonds as the go to thing because they have been around for so long.

That is interesting but perhaps you could share more information and someone aside from Cliff may have some insight? The main advantage of natural sharpening stones is that in general they last longer than synthetic sharpening stones. In addition, natural sharpening stones slowly remove material. These stones sharpen slowly which means that the end result is a little more refined and controllable. And you sharpen your knife on a completely natural product. That could also be an important advantage to many. The biggest disadvantage is that sharpening takes a little longer than when you use synthetic sharpening stones. And no natural sharpening stone is the same. The grain size and the coarseness of the stone cannot be accurately determined per stone. That is why an estimate is given of, for example, 6000 to 8000 grit. Especially when it comes to the higher grain sizes this isn't something you prefer. Ceramic sharpening stones

Also the other thing that most people don't realize is that although diamonds are harder then CBN at room temp when diamonds get hot from friction they also get softer then CBN and that's why a lot of big company's from what I have read prefer CBN grinding wheels better for large scale production when using steels that need to be ground down and are difficult to work with. Poltava Metallic CBN Sharpening Stones are used for sharpening knives using Hapstone, TSProf and Edge Pro sharpeners. CBN (Cubic Boron Nitride) is the second-hardest material after diamond. Metallic CBN stones utilize copper-tin alloy bonding for high endurance and low wearing rate. All I can say is these stones should be called for a brand name Rabid Piranha's because that's the best way I can describe them and to call them just Piranha's would not do justice as to how fast they cut. CBN offers excellent performance in sharpening knives of any steel. Due to its high resistance specs, CBN can be used dry without lubricant. This makes CBN the cleanest of the available sharpening stones. How to use
