A Game Changing Must Have Upgrade Kit
Two years ago I picked up the Worksharp Professional Precision Adjust knife sharpening kit as a total noob. Watched a handful of Youtube tutorials and sharpened my first knife. It's been a passion ever since. As other reviewers mentioned I also made a lapping film kit. It worked, but it's very slow going because it's downstroke only and the film requires constant cleaning while sharpening. If you own the Worksharp PPA sharpener, this 1.2k to 3k diamond resin kit is an absolute must have if you're as obsessed as I am with achieving the most mirror finished and unforgivingly sharp edge your skill level will allow. The grit panels, ceramic honing panel and leather strop panel that come standard with the Worksharp already deliver an excellent, super sharp mirror finished edge when used correctly. But continuing upward with this diamond resin kit delivers a dazzling mirror finish and unprecedented sharpness that makes your blade cut like whisper quiet magic. I just finished using this kit to sharpen a CJRB Tundra, a fantastic large overbuilt folder with a really cool chunky blade. I kept the factory 22 degree grind angle, and now this knifes edge has the most flawless mirror finish I've ever put on any blade. It's sharpness is at a level that doesn't even seem possible for a blade this thick. I use soapy water in a spray bottle when sharpening with all three diamond resin panels. And the super soft premium leather strop panel gets 1 micron diamond strop paste for the perfect finishing move. Worksharp hit it out of the park with these super high quality diamond resin panels. You'll be legitimately shocked by the master level mirror finish and ultra sticky sharpness they deliver. The standard Worksharp PPA is such an incredibly easy to use and highly effective sharpening kit as is. And this diamond resin kit is the perfect upgrade accessory that delivers a truly elite edge and mirror finish. Worth every penny. I hope this review was helpful to you.

Excellent Addition
Bought this add on kit for my work sharp pro looking to really get a better, sharper and polished edges on my collection. Used it today for the first time on my Spyderco Para 3 and love the results! - started with a 300 grit plate at 18 degrees. - went to a 400, then 600 grit plate next. - used an 800 grit plate to finish it off then did a pass with a ceramic plate. - then, I rechecked the degree angle with a digital meter as the directions say to do then used these 3 plates, ending with 3,000 grit. - I then did a pass on the strop to finish it off. Fantastic!

Really nice upgrade to PPA - turns it elite!
These stones make a great addition to the Professional Precision Adjust and basically turn it into the Elite minus the case. By the time you sharpen to 3000 grit you're up to a mirror shine on your edge and have created a REALLY sharp edge. It comes with the strop and two things of green strop compound.

If you’re OCD about sharp knives
This set provides three diamond sharpeners embedded in resin and one leather. They are intended to be used with the Work Sharp precision, adjust sharpener to which they attach with the steel bar to the magnetized holder. They are in my opinion a bit pricey for what you get, but because I am OCD about knife sharpness, I will buy them again when these were out.

Great product
I bought this to try because the blanks with lapping film was a pain in the butt to use. With these three stones I can get a mirror finish almost as good as when I used the lapping film but much quicker.
