Steel Lapping Plate

$48 AUD

Take your sharpening to the next level with this excellent method for flattening the backs of all Japanese blades!

      • Flat to within 0.02mm
      • 200x75x16mm

A flat back is essential to extract the maximum edge qualities and useablility of any Japanese tool. The solution we are providing our customers is the same as that promoted by our Japanese teachers. - take a flat steel surface, add abrasive, and get to work.

This lapping plate is manufactured from mild steel by a specialist engineering company a short drive from our Sydney HQ to our exact requirements.

We have specified its flatness to 0.02mm (two hundredths of a millimetre) across its span, and verified the first batch's tolerance ourselves. Both sides of the plate are ground to this flatness, giving you two surfaces to work on.

The plate is sized to match our large Suehiro stones, meaning it won't pose storage or transport issues by not fitting in a box or drawer, which is something that has annoyed us about other lapping solutions we've tried.

We haven't altered the side finish, as we want to be able to offer this essential piece of equipment at a reasonable price. If you'd like to refine yours, it can be done with a belt linisher or similar abrasive equipment.

Wear on lapping plates is a constant problem - though it may start flat, whatever abrasive is used will also eventually wear the plate to a point where it is beyond acceptable tolerance. Our wayt of monitoring this is to leave the grinding marks. The tolerance of the grinding marks is similar to that of the plate itself - measureable to hundredths of a millimetre. As such, they are a great way to monitor wear on the plate. If a plate is used beyond its tolerance, the machining marks begin to disappear, and it's time to flip it over to use the other side.

Plastic-free Policy:

Japanese Tools Australia is an environmentally conscious company and we endeavour to eliminate plastics in as many parts of our business as possible. Your purchase will be shipped in recycleable non-plastic materials, and we re-use cardboard and paper wherever possible in our shipping process.

Exceptions to plastic-free policy:

Unfortunately, we are required to dispatch some express items in pre-paid satchels and in such circumstances we have no choice but to use a plastic satchel. Please keep in mind these satchels are 100% recyclable. Our suppliers also use plastic in their packaging of some products, and we do not remove these protective measures before shipping. We are considering strategies to eliminate these two remaining sources of plastic in our shipping process. As many of our items are hand-made, they do not arrive to us or to you with extraneous packaging, though this is not the case for all of our products.

Breakage in shipping policy:

We pack our shipments in specialised materials to ensure that our customers find them in the same condition that we send them. If you receive your products in a damaged condition, please email with your order number and photos of the condition of the products within a week of collection. If an item is deemed to have been damaged in transit we will replace it with like kind at no extra shipping cost to the customer.

If you are unhappy with the condition of your product and it has not been damaged in transit, please refer to our returns and exchanges policy. 

We stand behind the quality of our tools. If a tool is found to be faulty or damaged in transit, we will verify the issue with you, and offer a refund or exchange when the problem is brought to our attention within 30 days from purchase. If problems arise outside of this period this policy will apply at our discretion. Where a refund or exchange is agreed upon, we will mail you a paid addressed bag to return your items, verify their condition once we receive them, and then process a refund or mail the new item.

If a tool is purchased as a present or the purchaser changes their mind, we will exchange for stock of equal value or store credit when we are contacted within 2 weeks of the purchase. We ask that the customer covers the cost of shipping in these instances. We will take a payment for shipping over the phone, send you a paid addressed envelope, verify the goods' condition once we receive them, and then mail the new item.

If a tool is damaged through improper use, we encourage you to contact us. We may not be able to exchange the tool, but may be able to offer advice on technique or recommend a more appropriate tool. Where possible, we encourage our cutomers to ask us questions about our tools' use before they purchase them. We can be contacted at or 02 9527 3870.

Sorry, we can't exchange gift cards.

Lapping plate

Must have for then first stage of honing any Japanese edge tool. Very happy to have one in the kit to ensure a razor sharp edge on my chisels and plane plates.

Gavin M.

Lapping Plate

Works very well. Used oxide powder to flatten and then water only to polish the new plane blade. Excellent results.

Nick P.

Flat and True

As advertised - very flat. Not having to regularly dress a stone when flattening and polishing the back of a new blade has been great. Fast postage and great service as always.
