Problems, parts and running costs

Summary

Five thin diamond plates labelled 400/600/800/1000/1200 grit with a honeycomb face, sold under a generic “Diamond Sharpening Stone” title — a budget kit for occasional home sharpening, not a precision plate set. Check whether you can mount the plates on a rigid surface: thin, unsupported plates are the most concrete complaint in owner threads.

Strengths

  • Five advertised abrasive steps from 400 to 1200 grit let you try edge repair, refinement and a finishing pass in one kit.
  • Diamond plates need no flattening and clean with water; upkeep is rinse, wipe and dry.
  • A KITANIS owner reported good results and no grit contamination in their own set.
  • The honeycomb recesses have a practical purpose: they give metal swarf somewhere to go instead of clogging the face.
  • A whole five-step kit has cost less than a single premium bench stone, so trying the format is low-risk.

Weaknesses

  • The plates are thin and low, so keeping a consistent angle is harder without a riser or holder.
  • One owner said all five grits felt and sounded almost identical after initial use, though the plates still sharpened.
  • The maker publishes no flatness tolerance, so guaranteed precision work like chisel backs is off the table.
  • No warranty period and no replacement plates are published; the eBay listing was sales-final.
  • A 1200-grit label does not promise a waterstone-like polish; abrasive geometry makes finish predictions unreliable.

Verified specifications

What this kit is

This is the KITANIS five-plate diamond sharpening set, identified by its five advertised grits and honeycomb faces rather than a model number; a US eBay listing ties it to UPC 768530111794. The maker’s landing page markets it for knives and woodworking tools and links out to an outside marketplace for purchase. The thin plates need a rigid, flat backing: an owner reporting on the KITANIS set mounted his on scrap wood and moved the adhesive support to the underside, and called the kit effective for the price. The exact plate dimensions are unconfirmed — an unbranded set with a closely matching description reports about 5.9 × 2.5 in, while the KITANIS eBay listing’s 6.3 × 4.41 × 0.71 in describes the package, not the working surface.

Using the plates

Use light pressure and let the abrasive cut. General diamond-plate guidance (DMT, and microscopy work done on other brands’ plates) says a new hone loses aggressive-feeling high points during break-in without losing cutting ability, so judge wear by metal removal rather than a scratchy feel. Rinse accumulated swarf off, dry the plates, and store them separated so the faces do not rub one another. The interrupted honeycomb face gives less continuous abrasive area than a solid plate, and a sharpening forum participant warns the grooves may snag a fine apex — a technique concern, not a demonstrated KITANIS defect. Diamond plates also give less sound and feel feedback than waterstones, so check the actual finish on a sacrificial knife instead of trusting the printed grit. If a cleaned plate no longer cuts, suspect genuine abrasive loss and replace it or contact the seller.

Is it worth it?

The exact KITANIS set last appeared on US eBay at $26.07 in a listing that ended September 9, 2026 — a historical offer, not a buyable one. Similar five-piece 400/600/800/1000/1200 sets without KITANIS authentication were listed at $19.29 on Walmart Marketplace and $28.72 on TikTok Shop in October 2026. At $20 or less for an authenticated new kit, the low cost justifies the thin-plate trade-off for occasional use. Above $25, the unbranded $19.29 set competes on raw cost, and for frequent sharpening the better-documented SHARPAL 156N (6 × 2.5 in, two-sided, $49.99) or the larger SHARPAL 162N (8 × 3 in, 325/1200 grit, $69.99, with a published flatness tolerance) at the brand’s US site are the sensible upgrades. The DMT DuoSharp 8-inch extra-fine/fine stone with base lists at $139.99 — a different budget class entirely.

Which model this is

This page covers the KITANIS five-plate diamond sharpening set with grits 400/600/800/1000/1200, UPC 768530111794. It is sold under a generic “Diamond Sharpening Stone” title, not a numbered KITANIS model. The Walmart Marketplace and TikTok Shop five-piece sets share the grit progression and honeycomb pattern but are not authenticated as KITANIS. No manufacturer warranty, manual or replacement-plate channel was found.
