Zen-Wu ZenSharp Station

The ZenSharp system from Zen-Wu provides you with the sharpening speed of water stones, combined with the durability and convenience of diamond stones—all at a price point that is unmatched.  The system is composed of a precision-milled base which accepts ZenSharp Cards. The base is heat treated three times to ensure lifetime flatness, and it has six legs to ensure flat precision like $100,000+ CNCs. Each card is plated with a specific diamond grit or strop material. They snap into the magnetic base with ease, allowing for quick interchangeability and compact storage. Just spray the card with a light misting of water or glass cleaner before sharpening, and get a razor edge in seconds. The cards are durable and low maintenance, never requiring the use of a heat gun to remove old diamond sheets from aluminum blocks.  When the cards wear out, they can be replaced at the fraction of the cost of a new diamond stone.  The ZenSharp system is available in a Starter Kit that includes: ZenSharp Base ZenSharp 45μm Coarse Diamond Card ZenSharp 20μm Medium Diamond Card ZenSharp 9μm Fine Diamond Card ZenSharp Ultra-Fine Strop Card (compound infused) Maple Card Holder Magic Eraser (x2) For professional chefs or industrial use, Zen-Wu also offers a Pro Kit that includes everything from the Starter Kit, plus: ZenSharp 60μm Ultra-Durable Coarse Diamond Card (steel substrate) ZenSharp 3μm Ultra-Fine Diamond Card  ZenSharp Kangaroo Leather Strop Card (compound free) Specific grits can also be purchased as individual packs.

You can get up to 8 different sharpening and honing surfaces for the cost of 2 stones and a strop. Their longevity is on a par with any diamond stone on the market and can be easily replaced for a fraction of the cost if worn or damaged. The diamond cards will sharpen your tools hundreds of times before wearing out, and it’s the exact same stones Zen-Wu uses in their factory to sharpen their chisels.  “Over-engineered” doesn’t exist in Zen-Wu’s vocabulary. They absolutely obsess over the details, and I’m here for it. The base plate has 6 feet instead of 4, ensuring complete flatness in the base that won’t sag over time. This is something you often find on ultra high-end CNCs as well.  That said, if you’re really pinching pennies, you can skip the base. Buy the cards individually, and just secure them to a flat surface.  The interchangeable magnetic plates are also incredibly convenient, especially if you work in a small shop. I wish I had these when I was working out of my shed. FAQ: How long will the cards last?  The diamond cards last for hundreds of tool sharpenings while remaining flat and true. Zen-Wu uses the same cards at their factory to sharpen chisels and plane irons.  Do I need an ultra-fine card?  No, you don't need the Ultra-Fine card unless you are making sushi. The Fine card is enough to give you a mirror finish.  What are the grits for each card? Coarse - 45μm  Medium - 20μm  Fine - 9μm  Ultra-Fine - 3μm Can I clean the cards with Windex?  Yes, you can use Windex or another glass cleaner on the cards.  Should I lubricate the cards before sharpening?  Yes, use water or glass cleaner, but not too much. Just a spritz so it’s not dry. If not dried thoroughly, liquids left on the diamond cards can rust filings left behind.
