## Questions & Answers

**Q: Does this come with the non skid holder?**
A: The one that is like $70. Comes with the holder

**Q: Is there grit on both sides?**
A: This is a single-sided stone.  It has grit on one side.  We do have the UltraSharp DC38 combination stone.  It has 300 grit on one side and 1200 grit on the other.  It is ASIN B01FPI7J6O.

**Q: How flat are these plates? Has anyone taken a dial indicator to them to measure?**
A: We check them with both the granite surface plate-jacks-dial indicator method and the machinist's straight edge-feeler gauge method.  I find both methods give the same result.  They typically test less than +/- .001 over the FULL length or width of the stone.   Given that each diamond particle on a 600 grit stone is roughly .001 in size, that is a pretty tight standard.  All Ultra Sharp stones come with a No Questions Asked 100% Guarantee.

**Q: These things slip and slide all over the place when used with recommended lubricant. How to hold in place?**
A: The best way is to use a Sharpening Stone Holder - https://www.amazon.com/dp/B07SHWBLHP?ref=myi_title_dp     They provide knuckle clearance and hold your stone in place while sharpening.

    A good diamond stone for all around use
  

*by R***C on Reviewed in the United States on May 2, 2023*

This plate is a very good sharpening tool for general use around the wood shop and the kitchen.  I am not a beginner, nor am I a professional woodworker.  I would recommend this to almost anyone - with a couple caveats.  One must have a bit of patience to break the stone in to get the max performance.  The requires following the directions very closely.  Take your time and let the diamonds do the work, do not try to force the plate to take off metal faster by pressing too hard.  Beginners may have a problem here, but anyone can correctly use this diamond plate.  I am very pleased with the performance over my old Diasharp plates I've had for too many years.  I sharpened several Henckel kitchen knives, 3 pocket knives, two plane irons, and  couple chisels just to get the thing to a point where I felt like it was fairly broken in.  Now, it cuts beautifully without any additional pressure at all.  I can feel the diamonds biting into the steel.  Great sharpener! I use this 1200 grit plate to maintain my bevels and prepare blades for the strop. I get an extremely sharp edge as a result.  If this plate hold up I plan to add a 600 grit version for blade/bevel shaping down the road.

    Great stones, better seller
  

*by R***  on Reviewed in the United States on June 1, 2020*

When I received the stones, I was a little disappointed to find that I had received a 600 grit instead of the 1200 grit that I ordered to go with the 300/600 grit set that I ordered at the same time.  More on that in a moment.Anxious I was to try these stones out, I immediately whipped out a dull kitchen knife, and within 10 minutes, with just the 300 and 600 grit stones, I had it sharp enough to cut a tomato without bruising it.  Mind you, this knife had about as much of an edge as a penny.  Ok, it wasn't quite that bad, but you get my point.  These things are great and I would recommend them without reservation.Now, at about 10 after 6pm, I hopped on Amazon and sent the seller a question about returning the extra 600 grit and getting a 1200 grit shipped out.  Within 10 minutes, the seller answered, told me to keep the extra 600 grit, and promised to ship me out the proper stone first thing in the morning.Amazingly, I literally have nothing to complain about, at *all*.  And this is the internet!Seriously, you can't go wrong with these stones and this seller.  Just go for it.

    It’s great
  

*by R***S on Reviewed in the United States on February 23, 2024*

I’ve been sharpening knives most of my life and for about the last 8 years I’ve used diamond plates. This plate is perfect. The grit is true after the break in period and there is no grit contamination what so ever. I will definitely purchase another when this one finally wears out.
