Japanese chisels

The Japanese chisel or nomi(鑿, のみ) is made on similar principles to the Japanese plane. There is a hard blade, called hagane attached to a softer piece of metal called the jigane.

Japanese plane

The Japanese plane or kanna (鉋) is a plane pulled towards the user rather than pushed in the manner of western style planes. They are made of hardwood, usually Japanese white or red oak. The laminated steel and iron blade is stout compared to western planes. Tapered in length and thickness the plane blade is its own wedge as it fits into a correspondingly shaped mortice in the body of the plane. Thus dispensing the need for a separate wedge to hold the blade in place, as is the case in most other traditional wooden planes. The chip breaker is held in place with a simple nail inserted some distance away from and perpendicular to the axis of the main blade. The chip breaker is not tapered like the main blade, instead it has bent "ears" that bear down on the plane blade. Chip breakers in Japan were introduced relatively recently during the Meiji period. The soles of Japanese planes also have different configurations intended for varying applications. The apparently simple design disguises a great deal of complexity.

Dovetail joint joinery technique

A dovetail joint or simply dovetail is a joinery technique most commonly used in woodworking joinery (carpentry) including furniture, cabinets. log buildings and traditional timber framing. Noted for its resistance to being pulled apart, the dovetail joint is commonly used to join the sides of a drawer to the front. A series of 'pins' cut to extend from the end of one board interlock with a series of 'tails' cut into the end of another board. The pins and tails have a trapezoidal shape. Once glued, a wooden dovetail joint requires no mechanical fasteners.

Preparation

A Japanese chisel usually requires some set-up, called shikomi(仕込み). The metal ring attached to the handle must be removed, the wood and ring filed to match, the ring replaced on the chisel and then the wood beaten down around the ring so that the mallet strikes the wood. The function of the metal ring is to prevent the wooden handle from splitting.

Sharpening

Japanese carpenters use waterstones for sharpening.

Sharpening stones, water stones or whetstones are used to sharpen the edges of steel tools and implements through grinding and honing.

Forge workplace of a blacksmith

A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature where it becomes easier to shape by forging, or to the point where work hardening no longer occurs. The metal is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub, which rapidly cools the workpiece in a large body of water. However, depending on the metal type, it may require an oil quench or a salt brine instead; many metals require more than plain water hardening. The slack tub also provides water to control the fire in the forge.

Hammer tool

A modern day hammer is a tool consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal, or to crush rock. Hammers are used for a wide range of driving, shaping, and breaking applications.

Chisel tool for cutting and carving wood, stone, metal, etc.

Plane (tool) tool for working with wood

A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine scale planing where a miniature hand plane is used.

Spokeshave woodworking tool

A spokeshave is a tool used to shape and smooth woods in woodworking jobs such as making wheel cart wheel spokes, chair legs, paddles, bows, and arrows. Historically, a spokeshave was made with a wooden body and metal cutting blade. With industrialization metal bodies displaced wood in mass-produced tools.

Mokume-gane

Mokume-gane is a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns, as well as that laminate itself. Mokume gane translates closely to "wood grain metal" or "wood eye metal" and describes the way metal takes on the appearance of natural wood grain. Mokume gane fuses several layers of differently coloured precious metals together to form a sandwich of alloys called a "billet." The billet is then manipulated in such a way that a pattern resembling wood grain emerges over its surface. Numerous ways of working the mokume gane create diverse pattens. Once the metal has been rolled into a sheet or bar, several techniques are used to produce a range of effects.

Mallet Tool for striking the workpiece or another tool with a relatively large head

A mallet is a kind of hammer, often made of rubber or sometimes wood, that is smaller than a maul or beetle, and usually has a relatively large head. The term is descriptive of the overall size and proportions of the tool, and not the materials it may be made of, though most mallets have striking faces that are softer than steel.

A shobo is a weapon, similar to the Emeici of China, which was used by the ninja of Japan for striking pressure points on an opponent. It was a piece of wood that was gripped by the wielder and was hung by a ring worn on the middle finger. Some versions were rings with a wooden peg attached on top. The ends were exposed and were usually sharp, which made them effective for paralyzing and even killing enemies quickly and without leaving a trace. They were easily hidden in the fists and were very lightweight and portable. They were usually worn in pairs. Many ninjas constructed their own shobo, although some were given from master to student.
