    With their forge welded blade, hollow back and socket ferrule / tang mounted hardwood handles, Japanese chisels are distinctly different in construction to Western chisels. This does not mean that are either superior or inferior, after all, they virtually do the same job. They are simply the Japanese approach, built upon hundreds of years of tool making tradition.

    Tateguya Nomi Mortise Chisel

    Tateguya Nomi are an effective mortise chisel. The Red Oak hardwood handle matched with a steel hoop means they are designed for striking with a metal hammer or wooden mallet. The chisels blade is the same thickness as the cutting edge allowing the tool to cut neat tight mortises. The blade is longer than a Oire Nomi, allowing you to work down into the deepest of mortises. The Japanese method of assembling chisels using a combined socket ferrule and tang makes them very secure and long lasting. Your Tateguya Nomi Mortise Chisel will deliver you with perfect mortises for as long as you work with wood.

    Why a welded blade?

    Your Tateguya Nomi chisels blade features a layer of high carbon White Paper steel forged to a softer wrought iron back. This produces a chisel with an extremely hard cutting edge cushioned by the softer steel blade. This blade making technique has been developed by Japanese Master blacksmiths over hundreds of years. These chisels stay very sharp and are perfect for working difficult softwoods and abrasive hardwoods.

    What is White Paper Steel?

    Japanese tools are made from either White Paper steel (Shirogami) or Blue Paper steel (Aogami), the colours refer to the paper used to wrap the steel by the manufacturer. White Paper Steel is a hard, high carbon steel with few impurities. White paper steel contains less carbon than Blue Paper steel chisels so therefore tougher and less prone to chipping.

    Why a hollow back?

    The hollow back is to aid the process of sharpening. The hollow creates a very thin area behind the cutting edge, and it is only this narrow section that requires flattening. Due to the hardness of the steel, without the hollow back the chisel would simply take forever to flatten. With age it is possible that hollow can interfere with the cutting edge, no worries, they chisel can be reshaped by hand to extend its life indefinitely.

    Why a socket ferrule and tang?

    Western chisels are generally constructed in two ways - socket or tang. Socket chisels are where the handle fits into a socket forged as part of the blade. Tang chisels are where the blade tang is inserted into the handle supported by a steel ferrule.

    Modern Japanese chisels are a combination of socket and tang chisel designs. A heavy tang is inserted into the handle supported by socket shaped ferrule. This results in a very solid, long lasting and self-tightening chisel.

    Why a steel hoop?

    The steel hoop protects the top of the handle from the blows of steel hammers commonly used in Japanese woodworking. Traditionally, fitting the steel hoop was the responsibility of the purchaser. Modern Japanese chisels are generally supplied with the hoop fitted in position. The hoop and chisel handle may be adjusted as the chisel ages.

    A proper mortise chisel

    The blade of your Tateguya Nomi Mortise Chisel is the same thickness as the cutting edge. This allows you to cut neat tight mortises. The blade is also longer than a Oire Nomi, allowing you to work down deep into the mortise joint. Chop perfectly proper mortises with your Tateguya Nomi Mortise Chisel.

    Welded White Paper steel blade

    Your Tateguya Nomi chisel has an extremely hard White Paper steel cutting edge cushioned by a softer steel blade. This means your chisel will stay super sharp even with extended use. Japanese chisels are ideal for difficult soft woods and resist the natural abrasion often encountered with exotic hardwoods.

    The hollow back

    The back of your Japanese chisel is very hard. The hollow back means flattening your chisel when sharpening is far less time consuming. Spend more time woodworking and less time sharpening.

    Socket ferrule and tang assembly

    The socket ferrule and tang design make a Japanese chisel a very secure, stable and long-lasting chisel. Striking the chisel forces the handle ferrule deeper into the socket, tightening the sockets grip even further.

    The steel hoop

    The steel hoop protects the top of the handle from the blows of steel hammers commonly used in Japanese woodworking. The handle of your Tateguya Nomi Mortise chisel is protected even when using the heaviest or hardest of mallets.

    Hardwood handle

    The handle of your Tateguya Nomi is made from Japanese Red Oak. This material is hard and dense, perfect for making tool handles. The chisel handle also bulges in the middle, strengthening the chisel further and helping the chisel to fit comfortably in your hand.


    Your Tateguya Nomi chisel comes packed in a secure cardboard box - your chisel will arrive in perfect condition. Also means it is a thing of beauty, matched only by the pleasure you will find using it.

    A tool for life

In addition, Japanese chisels are designed so they may be maintained as they age and wear, they can even be modified. For example, the hollow back of the chisel may be modified to extend the chisels life indefinitely. The handles are made so the steel hoop can be repositioned as the end of the handle wears through heavy use. You can even make your own handles and fit them if you so desire. These are the tools of the true craftsperson.
