Premium Kanna Making Set

$1,100 AUD

This kit brings together the work of three top-flight tool makers, with our little Australian touch. It includes specialist tools that can be used to build a Japanese plane block (dai), a blade for that dai, and a block of Australian Jarrah that we had earmarked for one of our own plane projects, until we decided that someone else might enjoy it, too.

Every tool here is special in it's own way.

The core of the kit is the 70mm Aogami plane blade set (blade and chipbreaker) handforged by master smith Yamamoto. These are the same blades that we have used in plane-making classes with Takami Kawai of Kyoto's Suikoushya carpentry, and having seen them used to make beautiful and functional planes under his guidance, we have also used them in our own plane projects. Yamamoto's work speaks for itself, with the blades taking and keeping phenomenal edges while being a pleasure to sharpen.

To form the channels of the dai that will eventually hold the blade, a specialist saw must be used that can cross-cut hard timbers, leave a fine kerf without the use of a spine and is thin enough to fit through the roughed-out mouth of the plane. Although there are a number of workarounds, the hand-made Osaekiki Nokogiri by Hishika is a beautifully finished tool that has been especially crafted to fulfil this role. 

Although the three chisels included in this set are not the only ones you'll need (a sharp 18-24mm chisel will be helpful for excavating the waste), they are all hand-forged with white paper steel edges by master smith Ouchi-san for very specific purposes in the plane-making process. The three chisels included are;

  • A 1.5mm super-fine chisel, used for tuning the sides of the blade-holding channels. This chisel can be bought separately here.
  • A 9mm cranked neck chisel, fantastic for tuning the bases of these channels.
  • A 24mm flat-tip chisel, with an extremely low profile that can be inserted through the mouth of the plane to tune the bed or the koppa-gaishi 

Finally, we are including a Jarrah block that we have dimensioned appropriately for use as a dai. We have a few experiments lined up to make Japanese planes from Australian timbers, and while we are yet to make a dai from this species, it seems to have the appropriate qualities of hardness and stability that we think will allow it to produce a worthy block.

We have only one of these sets for sale. We will provide it's future owner basic documentation that we have followed when making our planes, suggestions for further reading, and advice on how to best sharpen these blades and go about the kanna-making process. We are yet to encounter tools such as these in Australia, and are very keen that their owner be given the knowledge needed to use them well.

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 recyclable 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.
