"This is now my only sharpening system (and I have tried them all). Enough said."
The ZenSharp is a precision-milled aluminum base that accepts interchangeable sharpening cards, held in place magnetically. Assembled, it holds a flatness tolerance of 0.015mm (~1/2 thou). Swap cards to change grit without moving the tool or breaking a setup, faster and cleaner than managing a stack of water stones at the bench.
ZenSharp cuts quickly like a water stone, and needs no flattening or soaking like a diamond stone. A light spray of water or glass cleaner is enough lubrication, and the cards never need to be peeled off with heat the way sheet-style diamond plates do.

Pro Kit (for chefs and industrial users):
For most woodworking, the fine card is sufficient to finish an edge. It will already leave a mirror polish. The ultra-fine card is for sushi knives and other cases where the absolute finest finish matters.
A single diamond card lasts for hundreds of sharpenings while staying flat and true. We use the same cards at the factory on our chisels and plane irons.
A note on technique: the diamond layer sits on a PET sheet bonded to a thin steel backing. If a blade corner digs into one spot under heavy pressure, it can damage the PET. Keep full lateral contact across the card when sharpening. No single-point grinding. For why we use a soft substrate rather than steel, see On Soft Substrates.
Patented. A 3D-printable storage box is available here.
Each card is rated by its micron, the size of the particle that actually cuts. You can see where the ZenSharp grades sit among every other sharpening abrasive, on one micron scale, on the Grit Table.

"This is now my only sharpening system (and I have tried them all). Enough said."
"Absolutely brilliant! I’m a novice woodworker and have always struggled with sharpening. The ZenSharp system is foolproof, I used it in conjunction with the Katz-Moses sharpening jig and got amazingly sharp edges and micro bevels on my old chisels as well as a mirror polish. I couldn’t be happier."
"Very good sharpening system."
"I have a few of the Zen Wu tools and I would love to eventually get the pocket plane. So, what I like: I love the base, one of the best out there. The plates lock in tight and have never moved. Love the plates with embedded diamonds. I like them so much I wish they were all embedded diamonds. The paper ones have to be pulled back on like the scary sharp system. As soon as you push any error will cause the paper to tear. If all the plates had embedded diamonds I would throw every other sharpening tool away."
"One amazing set."
"Very well made and packaged. I really do enjoy the quality of Zen Wu"
"Genial producto, muy recomendable."
"I am learning how to sharpen using your system. It is simple and straightforward and I am seeing rapid improvement in my results. Very encouraging, very effective"
"tore quickly, loaded with swarf quickly"
"Amazing sharpening system. I’m a newbie, and this has made my sharpening super easy, clean, neatly packed, and it doesn’t take any space to store. I’m very pleased with it, and I will definitely buy more from Zen-wu. I love it!!!"
