2 Stones in 1 for a Keen Edge

A dual sharpening stone, the Fallkniven DC521 features an aggressive diamond stone (the yellow side) and a slow, fine ceramic stone (the dark side). For most sharpening tasks, you’ll use the diamond side. Simply stroke the edge of your blade along the edge up to 10 times on one side; then flip the knife over and repeat the process. If you want to get your knife to a super fine edge, turn the stone over to the slow, fine ceramic side and use the same technique. Because it’s finer, it takes off less material, thus honing the edge further. Measuring over 8 inches long, the stone is long enough that you can take broad strokes, but not so long that it’s hard to bring with you.

Your comments bring a whole other level into this discussion.... First, let me say this: All abrasives, whether paper/stones/ceramics/diamond plate, are going to have some variance in size for individual particles. The best we can ever hope for is an accurate "average" for the piece. Even with ceramics, Fallkniven should be able to tell us that based on measurements taken from the scratch pattern they leave behind. Since SOME of their ceramic products DO mention it, they should be able to say for all. Joe Shmoe's version of "extra fine" might be my "medium". For them to just say it works tells me nothing. But, on to the new stuff: Speed and grit aren't always directly related. Lower grid GENERALLY remove steel faster, but it's not always a direct correlation. I've owned multiple stones listed with the same grit, that do appear to leave similar scratch patterns under a loupe, that work at much different speeds. Therefore, based on the appearance of the scratch pattern, i'd say they're the same grit, but one is fast and one is slow. Then I've got this 2k stone that removes steel as fast as the 1k stones I've had, but leaves a finer scratch pattern. I'd still say that's a higher grit stone, and it's just a fast cutter, i wouldn't call it coarser because of its speed. It's about the cutting ability of the particles used, not just about their size. It also has a bit to do with the material the abrasive particles are bound with, how much the abrasive sticks up above the surface, how quickly the binder wears, and how often new abrasive is exposed to the surface. I do get what you're saying, i just think you're confusing matters when you say you'd consider a faster stone to be "working at a higher grit" To me a whetstone has 3 main characteristics; grit rating, hardness, speed. All 3 have to be looked at together in order to guess at what the stone might be like before buying it. -Grit is grit, if their ratings are accurate and you know what scale they're measuring by, that should tell you the level of finish it will leave. -Hardness will tell you how quickly the stone will wear, how much it will dish, how often you'll have to flatten it. Now, softer stones will release fresh abrasives more often, so they often work faster. But, depending on your usage and how flat you need it to stay, you'll spend more time flattening, half the stone will be wasted and overall it will just wear out quicker -Speed is the one thing that will always be subjective....but like i was saying above, you can find fast and slow stones all up and down the grit scale All that long winded rambling aside lol What's the stone you got? Always interested in trying new ones that cut fast and are reasonably priced 😁
