Question: colors of the stones?
Document: the shipment came in a very timely manner and the DMT sharpening stones are top quality. I use them to home my woodturning tools. Really helps to get a razor sharp edge on these tools.
Kitchen knife or chisel, they must be sharp for work and safety. My tools are not always sharp, but sharpened cutting tools ARE pleasure to use. DMT diamond stones give very good value for the money.
This is a great tool. My only complaint is that DMT's sense of &#34;coarse&#34; isn't the same as mine. The coarse side of this stone is about the same as a medium India stone, and the &#34;fine&#34; side is a bit more abrasive than a washita stone. That makes this pair of stones useful for maintaing kitchen knives, once you have them in shape.
I have been sharpening knives, axes, wood planes and chisels for a few decades and until recently had not "discovered" these diamond tools. What a revelation! Now I have to find someone to give all my old fashioned stones to. And I have a pile of them!This tool is high quality and does just what it says it does. And it is simple to maintain and store and use.Be caareful with it and be careful with the blades you sharpen on it! Great tool!
I love these diamond sharpening stones. This one cuts fast and does a good job sharpening. Obviously, if I was better at holding the correct angle I'd do a better job, but that's my weakness, not this stone. I'll keep practicing! !The diamond stone wears well, doesn't wear a &#34;curve&#34; like a rock stone, so it will last a LONG time!
I bought the course/fine stone. There isn't a huge difference between the two sides but if your blade doesn't have nicks in it the stone will put a quick decent edge on it. I use a couple different finer grit oil stones to refine the edge to a razor after I use the DMT stone. I will most likely buy the extra fine and extra extra fine stones as well
What do I like so much about this sharpening stone?I have tried all of the different whetstones out there, as well as sharpening stones, honing rods, etc..I always sharpen my own tools and also my own chef's knives as well as a few camping knives. This is the best diamond sharpening &#34;stone&#34; on the market. For example I must have used my first one for over four years and just a month ago bought this one to replace it!
water to wash away debris makes this benchstone easier to use around the home. fine/coarse is more like fine/medium but both cut pretty fast.
takes less than half the time of a regular stone, and this product is well worth the money
it does not appear used, its just disappointing when you receive items that look shady. the item seems to be in working order and perhaps I'm too picky, but 3 stars for now.
Answer: yes
