Banshu Miki UchihamonoBanshu Miki Forged Blades

For last years of the Azuchimomoyama era, Miki Castle was attacked by Hideyoshi Hashiba and fell, and town of Miki was destroyed.
After Hideyoshi exempting from tax of townsman, and planning revival of town, for Shinto shrine, Buddhist temple, the rebuilding of house, carpenter craftsmen gathered from each place and were connected for development of carpenter tool of Miki afterwards.

After the siege and final fall of Miki castle toward the end of the Momoyama period (1573-1600), carpenters from various parts were drawn here to rebuild the town. Along with them came many smiths to forge the tools they needed and forging developed as a craft here.

By the end of the Edo period (1600-1868) large quantities of forged blades for such things as saws, chisels and planes were being made here, and it is still one of the country's prominent centers for the production of bladed tools, the saws and chisels in particular being the envy of the world.

    "Banshu Miki Uchihamono" is ultimate carpenter tool which professional chooses. Saw (saw), plane (plane), chisel iron (iron), knife (kogatana) are appointed now by Officially designated Traditional craft products. We will see main passage of process of manufacture of chisel here.

    Process 1: Forge welding (tansetsu)

    We have toward soft ground iron (jigane) which we heated by fire of 1,100 degrees Celsius - 1,200 degrees Celsius with forge welding agent (tansetsuzai) and join firm steel (we do not tear off) that it is on part of blade. Shear steel (steel of pike conger) is carbon steel and can become blade firmly as we include carbon.

    Process 2: Forging (forging): Ear beats

    We beat so that steel is united with ground iron and forge blade which we joined. We forge so that steel coils itself around ground iron to the side then. It is hoda chitoiimasu in forging part of ear (former part with blade) here. And we cut into chisel one order.

    Process 3: Forging: We hit axis

    Next forges axial part. While being careful not to overcook part of ear, of contralateral caudex begin to forge. And we make middle stem (basket) entering pattern.

    Process 4: Fire polishing

    Furthermore, we put in the fire to fix form. Temperature-controling is important and can enter in fire of 950 degrees Celsius - 1,000 degrees Celsius not to spoil strength after roast because the point of a sword is thin as for the chisel. After having provided, we make closing a bargain earnestly and make while fixing width, thickness, form.

    Process 5: Anneal (we bake and cool down)

    After having fixed form, we heat up again and bake and become dull. We gradually cool at temperature of 740 degrees Celsius - 750 degrees Celsius using straw ash (we double straw) for annealing from old days. This is because it makes it easy to process it. Crystal particle of steel of chisel varies from coarse thing to crystal which we equalized finely by process to here.

    Process 6: Abrasion

    Next is polishing. At first with wild file of caudex round off and do rough chance of the back. Furthermore, we hang buff abrasion to smooth off the surface.

    Process 7: Quenching

    After having polished, we put roast. We lose spot before quenching and paint with dust to make it easy to quench. We put roast in the electric furnace of 780 degrees Celsius - 800 degrees Celsius for 2-3 minutes. Enter water quickly and cool afterwards.

    Process 8: Temper

    And we return roast after having taken distortion that we occurred by quenching. At first do temper in oil, and is water; is over, and salt of temperature of 150 degrees Celsius - 180 degrees Celsius be accompanied; grilled; return, and do. Black luster occurs on the surface doing it this way.

    Process 9: Finish abrasion

    It is finally finish. We polish up the back, leader and steel of ear. Chisel that the sharpness is sharp is completed in this way.

    Genuine strength that is not drained in the times, **shi of Miki

    The history of Miki hardware is old, and it dates back until old days of 200 years. We heard secret of strength that we continued still living for today after long time to chisel craftsman Kazumi Takahashi in this way 55.

     

    Product which changes with the times

    Story of Takahashi "who made only chisel for clogs in old days" is surprising. Speaking of chisel, we associated chisel for building, but made chisel to finish between tooth and teeth of clogs in those days. In addition, when ornament of bear of Hokkaido became boom at one time, it is said that we were chased for the making of chisel for sculpture, but there is not those demand now. It was replaced and has begun to make special chisel for main occupation to make Buddha statue and ranma. Takahashi says, "this was good" heartily. Order comes by name now. For example, order continues from Inamimachi, Toyama that is famous for the making of ranma for 15-16 years. Actual feeling stays for words to say saying "we are really glad that we have you understand the good own chisel toward the genuine craftsman".

    It is natural to have feelings

    Chisel which Takahashi makes is handmade one by one. Only as for the thing that it is special. Order from craftsmen making Buddha statues is careful. That person who writes to design in detail, and orders comes among them. When visit each time when take effort, and it is tough; "it is natural to do it. We followed for a long time simply because we had feelings, and powerful answer came back saying we want to be particular more and yet more from now on. It is certain that we continue meeting request of nation-wide fan which we hate when it is not chisel of Takahashi from now on.

    Son that successor makes homepage

    Lack of successor is place of Traditional Craft headache. However, excellent successor is broken to Takahashi. However, it is said that we gave up at first. This is because Den Takahashi three of son became inheritor after office worker life of six years. It is said to be when we ask about motive saying "we began with light feeling as it was to paper fortune which we pulled by chance for New Year holidays" when "good though we inherit business". "We were optimistic when it would be easy, but there was nothing at all for three years of the beginning. We begin to be able to finally do it little by little from the fourth year and tell to have become interesting. We were still training ourselves, but we established homepage and we brightened eyes and told, we want to convey splendor of Traditional Craft with the technical acquisition in the future. On the other hand, close parenthood warmed heart although it was stern teacher and pupil.

Characteristic

Training of sum iron was succeeded to from the Edo era, and, in the Meiji era, dajimbutsu of many kinds was developed by new technique. Craftsman engaged in Officially designated Traditional craft products directly occupies 20% of the whole and follows tradition even now.

Techniques for forging Japanese iron were first passed down from the Edo era and, with the introduction of new techniques in the Meiji era, many varieties of cutlery have been developed. Even today, craftsmen directly involved in making traditional crafts represent 20% of the total workforce, keeping the tradition alive.

How to make

When it is to chisel, plane, knife, we heat iron and carbon steel in furnace and do forge welding more to hit mallet. We heat molding in furnace and we train with mallet while making mud coating and finish. Saw, iron of waitori riga craftsman is the your chance to show what you can do, and craftsman of Miki has this splendid technique.

Using chisels, planes and knives, iron and carbon steel are heated in a furnace and welded together by hammering. The products are shaped by heating them in an oven and forging them by hammer while caking them with mud. Straightening the iron to relieve inner stress with a saw or a trowel gives Miki craftsmen the opportunity to show their abilities and the wonderful techniques they have mastered.
