A Tour of the Workshop
Walk through the shop and see where it all happens from charcoal making to finishing a blade. The workshop set up is fairly simple and requires but a few basic tools. All of the tools here are either antique, handmade, or both. Many blacksmith tools can be made by the smith, including the forge, specialized tongs, hammers, and chisels.
The fuel for the forge is made from construction scrap and deadfall pine wood in an outdoor kiln.

The forge is a simply constructed bladesmithing charcoal forge. Two rows of bricks contain the charcoal but allow for long pieces to be heated in the centre. In addition to heating the steel to shape blades, the forge can be used to anneal, silver solder, and patinate copper.

Fuigo Box Bellows
The bellows provide the air to the forge to increase the temperature of the fire. Japanese style box bellows are constructed almost entirely of wood and supply a highly controlled air blast to the forge on both the push and the pull stroke.

Bladesmithing anvils need not be more than a rectangular block of steel, but this eighty year old beast allows me to do other blacksmithing work from time to time. The anvil is the table which supports the steel as it is hammered into shape. Portable or part time anvils are good in the 100-130 pound range, a shop anvil for regular work is better in the 150-250 pound range, depending on the work. For Japanese sword style bladesmithing, a thin layer of water is used on the anvil to keep the fire scale off of the blade as it is forged.
Finished charcoal is chopped and stored in a metal bin for use in the forge. The steel bin helps keep the charcoal dry, and prevents sparks from igniting the large stored supply before its time. The shovel was made from farm machinery almost a century ago by a prairie blacksmith.

Blacksmiths must have a variety of long-handled tongs for holding hot steel as it is shaped. Tongs must hold steel tightly to avoid slipping or dropping under the forces of hammering. This set has been modified from a more standard type and is designed specifically to hold the tapered tangs of tanto as they are in the later stages of forging.
Bladesmiths often use two or three different hammers during the process of forging a blade. Initially, a heavy hammer reduces the stock to approximate dimensions and then a lighter hammer takes care of the controlled shaping and finishing through the sunobe stage and beyond.
Hammers may be made by the smith for specific weight and shape preferences. A recommended weight range for the large hand hammer is 1.5kg-2kg (~3.5lbs-4.5lbs) and the smaller one is 1.2kg-1.4kg (~2.5lbs-3lbs). The large mukozuchi for a striker is usually between 3貫/kan (11.25kg / 24.8lb) and 1貫/kan (3.75kg / 8.26lb).

A blacksmithing standby, the leg and thick forged jaws can handle most anything from filing to hammering. The vise holds the blade while it is being profiled with a file. In addition to very sturdy construction, a post vise has an iron leg that goes straight to the floor under the rear jaw. This transfers the energy of hammer blows to the floor instead of breaking out the bolts mounting it to the bench. The long handle allows you to really clamp hard on a piece of iron, and the smooth jaws do not mar the soft, hot iron.
A vise should be mounted at the height of a ‘smith’s elbow for operations such as filing and bending. This tool was forged around a century ago and is on its last, and only, leg. It is still mounted to the original wooden stand I have used for it since 1992.

The staple vise solves the dual problems of getting clear access to the sides of a blade, and of steel jaws marring the soft steel of the tang. Various wooden wedges are used to hold a blade securely for scraping and filing.

Hot water provides a proper cooling rate for clay coated steel to become hard without cracking. The water is heated with waste heat from the forge prior to yaki-ire. This tank is aluminum, but will have a limited lifespan due to the alkalinity of the water from bits of floating charcoal ash in the shop.

Sun Tiger Hand Grinder
A hand powered grinding wheel is occasionally used to remove the first of the hardened steel from the edge before working with waterstones. Slow speeds keep the risk of overheating the steel to a minimum.

Togi Dai (Polishing Bench)
The stones sit on a wooden support above the tank, fresh water is splashed or poured over the stones as needed and the tank catches the swarf. Finer and finer stones are used as the blade takes shape and becomes smoother.

The post drill is used to create the mekugi-ana in the tang of the blade. Turned by hand, progress can be carefully watched and adjusted as necessary. This machine was made in Canada around the turn of the century and still has some miles left to go. Cast into the frame are the model number, 614 (from 1914), and the words, “Can. Blower & Forge Co. Ltd. Kitchener, Ont”.
