Michael, Anna, and Gabriel Bell of Dragonfly Forge are happy to announce Tomboyana Nihontō Tanren Dōjō’s schedule of classes for the 2010 school year! We are looking forward to having much fun in the forge again! We will certainly enjoy seeing returning alumni and new students both.

Our Basic Forging Course is certainly the most popular class we offer, four sessions of which are currently scheduled for 2010. October is once again left open with the possibility of fifth Basic Forging Course being scheduled, if there is sufficient interest. We will also be offering two sessions each of our Habaki and Kajioshi Courses, with a special 5-day combination Kajioshi-Habaki Course new for 2010 in May. There is also a Koshirae Course, and following that aTsuka-maki Course scheduled in August.

All of our classes run from 9 AM to 5 PM on the dates of the session. Lunch is provided.

Space in our school is limited per class, and a deposit is required to secure a seat, which can be paid through our site which links to a secure PayPal site. The remaining tuition is due on the first day of the course.

Basic Forging Course

This is a hands-on course designed to give the student a working familiarity with the tools and metals utilized in the forging of a sword blade. Each student will forge his own blade of at least wakizashi length from forge-welded steel cable. Skills learned will include forging, grinding, filing and heat-treating, with attendant emphasis on metallurgy and proper shaping and aesthetics. All tools, fuel, and material included.

The price of the course is $1250 and is limited to four students per session. A deposit of $250 is requested, refundable up to 60 days before the session begins.

Koshirae Course

– Carving and Shaping a Sword Mounting

Students will learn how to carve handles (tsuka) and scabbards (saya), as well as fitting tsuba, fitting seppa and fitting fuchigashira to the tsuka. Included in the course is the making of mortise and tenon kojiri and koiguchi, and kurigata made from buffalo horn. Tools used are traditional saws, chisels, knives, and planes and will be on hand. Alder wood will be provided, although students may bring their own.

Tools and materials will be provided, but students should have their own sword blades with a well-fitted habaki, plus tsuba and fuchigashira.

The price of the course is $1250 and is limited to four students. A deposit of $250 is requested, refundable up to 60 days before session begins.

August 2-6, 2010


Tsuka-maki Course

– Handle wrapping

A two day session covering the silk wrapping on a Japanese sword handle. The course will cover preparation of the handle before wrapping, folding the papers, measuring the tape, wrapping and tying the knot. Students should bring their own handles with ray skin already wrapped or inlaid. Silk for the wrap can be purchased from the school at $5 per foot. All tools are included.

The price of the course is $500 and is limited to four students. A deposit of $100 is requested, refundable up to 60 days before session begins.

August 7-8, 2010


Kajioshi Course

Kajioshi means “smith shaped” and is the grinding of the blade prior to its being sent to a polisher. It has been observed that Western craftsmen, although comfortable with the technology, have a difficult time shaping the blade into a harmonious form. This course is designed to teach how to see and correct deficiencies in shape and geometry. Students should bring a sword blade where the shape is “just not right”. These will be studied and corrected, either by grinder or by water stone. Tools will be provided.

The price of the course is $500 and is limited to four students. A deposit of $100 is requested, refundable up to 60 days before session begins.

May 1-2, 2010
July 10-11, 2010


Kajioshi-Habaki Combo Course

NEW FOR 2010!

The Kajioshi-Habaki Combo Course is a new addition for the 2010 school year. The course, which is a combination of our two-day weekend Kajioshi and Habaki Courses, was created due to interest by alumni of Tomboyama Nihontō Tanren Dōjō in continuing their studies in the Japanese sword arts by beginning to mount, the blades they forged here during a Basic Forging Course. And the first piece in a completely mounted Japanese sword is a habaki.

However, to make a well-fitted habaki, the portion of the blade underneath and around where the habaki slips into place at the machi, known as the habakimoto, must be completely shaped . This meant that in order to take the Habaki Course, a student had to either provide a old blade in need of a new habaki or have already performed kajioshi, the initial shaping performed on water-stones by the smith, on their own blade. Given that our Kajioshi Course is a two-day weekend course as well, students, who are traveling from across the country, or internationally, were interested in coming for a longer stay to study the Art.

By combining our Kajioshi and Habaki Courses into a five-day week-long class, students can bring their unrefined grinder shaped blades to class and, using their blade as a first-hand lesson, help to develop the aesthetic eye, shaping the blade on traditional Japanese water-stones.

The extra day of classes will give students time to properly prepare and refine the habakimoto, where the habaki will fit, with water-stones, laying the good foundation needed to make a well-fitted and ascetically pleasing habaki.

Once the student has properly shaped the nakago and habakimoto area with the waterstones, the final two days of the class will be spent forging, soldering, and shaping habaki of copper fitted to the student’s blade.

The price of the course is $1250 and is limited to four students. A deposit of $250 is requested, refundable up to 60 days before session begins.

September and October, 2009 Basic Forging Courses, End of the School Year.

October 23rd, 2009

With the conclusion October Basic Forging Course, the Tomboyama Nihontō Tanren Dojō 2009 School has come to close.

September 7-11, 2009 Basic Forging Course

Our September 7-11 Basic Forging Course was attended by three students, Jacob, Niels, and Soko.  Niels blade was successfully heat-treated on the first attempt. Unfortunately, we regret to report that Jacob and Soko’s blades both cracked after heat-treatment, something that has rarely happened at the school.  Luckily, Jacob had the chance to reforged part of his broken wakizashi into a tantō, which successfully survived yaki-ire. The heart-break of a fatally broken blade is something every smith experience sometimes, including professionals, but we hate for the lesson to be learned first hand by students of our swordsmithing school. We believe Jacob and Soko still both enjoyed the class, a testament to their good attitude and understanding of the art.

The October 12-16 Basic Forging Course was a special session scheduled later in the year due to interest.  It was attended by one student, Harry, who forged a beautiful blade of forge-welded cable steel.

Looking Forward to the 2010 School Year…

The October Basic Forging Course concluded the 2009 School Year for Tomboyama Nihontō Tanren Dojō. In the next month we hope to schedule the 2010 school year. Once it is scheduled, we will post it online and students may begin reserving places in the various sessions. We are looking forward to another great year of classes!

August 2009 Alumni Kajioshi and Bonji Courses, Oroshigane Seminar

September 19th, 2009

Last month, we were thrilled to have four alumni of Tomboyama Nihonto Tanren Dojo return to the school to attend our August 7-9, 2009 Oroshigane Seminar.

34. August 2009 Oroshigane Seminar

Unscheduled August 2009 Bonji and Kajioshi Courses

Three alumni joined us two days earlier for special unscheduled two-day classes in bonji and kajioshi.


Students Jeff and Allen carved bonji in blades they had forged themselves of folded cable and Steven studied blade shaping and practiced achieving subtle refinement of shape on the water stones.

Teaching Kajioshi

August 2009 Oroshigane Seminar

“Oroshigane” is a Japanese term used of the processes a smith uses to adjust the carbon content of sword steel, and also used to  refer to the steel made from such processes.

For the seminar, we began with two forms of iron, electrolytic sponge iron and antique wrought iron, which we added carbon, through the process of carburization, to create steel.

Both electrolytic sponge iron and antique wrought iron are extremely pure forms of iron.  In Japan, electrolytic sponge iron is known as denkaitestu, and is sometimes used for oroshigane by swordsmiths who cannot attain tamahagane, or are interested in making their own steel.  Electrolytic sponge iron is literally “distilled iron”, a byproduct of the electric arc furnace.

True wrought iron is an antique form of commercially pure iron. Although many products are described as wrought iron today, such as guard rails and gates, they are made of actually made of mild steel and only retain that description because they were formerly made of wrought iron.  Because of it’s corrosion resistance, wrought iron was often used for marine applications in the past.  Like denkaitetsu, wrought iron is an extremely pure form of iron, although it is also high in silica.  It is distingiushable from mild steel by its fiberous grain.  Because it is no longer made on the industrial scale, wrought iron is sometimes jokingly called “unobtainium”.

Modern steel contains several alloyed metals and impurities, not found in nihonto.  Some impart desirable qualities or counteract the effects of contaminents.  Most important of these is manganese.  Manganese prevents phosphorus (an embrittler) from migrating to grain boundaries and creating weaknesses, and also promotes deep hardenig. But manganese also makes steel shinier and more reflective, two qualities which make an sword forged from modern steel instantly discernable from a traditionally made Japanese sword.  By beginning with a very pure sources of iron and adding only carbon, we are able to produce a steel that is compositionally the same as tamahagane and visibly indistinguishable.
