  1. a lovely film made by some talented folks... In a forge on Vancouver Island, reclaimed steel is turned into tanto. Directed, Photographed, and Edited by Trevor Komori Location Sound: Sean Brouwer B Camera Operator: Liam Leyland Music Composed by Kurtis So Production Assistants: Vivian Hu & Judy Zheng still images | behind the scenes | making this tanto

  3. a collage of some old photos via tony... more info and additional video: http://islandblacksmith.ca/2018/07/passing-of-louie-mills-yasutomo-康友/
  4. nice work, great use of a barrel...looked plenty enough carbon by the break test, and fairly low manganese by the hamon placement too...i have a real old one sitting in the shop waiting for the day...the proportion of mild to higher carbon looked pretty similar to kōa-issin-tou in the etch...some informative info and details on construction for those wanting to research, great steel and great swords: http://ohmura-study.net/998.html https://www.japaneseswordindex.com/koa.htm
  5. fairly old low alloy carriage spring...traditional clay and water quench using a charcoal forge...~1mm thick layer of roughly 1:1:1 natural clay, charcoal powder, and polishing stone powder...blade is about 29cm long (nagasa), 2.3cm wide (motohaba) and 6mm thick (motokasane)...close up of the rough kajitogi polish done with very coarse waterstones (torajirushi 80#, lobstercarbon 120#) to check the hamon placement... watch it happen below (more info here: http://islandblacksmith.ca/process/)... yoroshiku!
  6. for posterity, here is the original video: and on a playlist of traditional swordsmiths:
  7. here is a (slowly) ongoing series with some info on the classical approach: http://islandblacksmith.ca/tag/tanto-geometry/ in particular the tang/machi geometry: http://islandblacksmith.ca/2014/06/classical-tanto-geometry-nakago-tang/ and the habaki 's machigane: http://islandblacksmith.ca/2014/10/classical-tanto-construction-habaki-の-machigane/ i always recommend studying antiques and making kata to get a feel for the finer points of tanto geometry: http://islandblacksmith.ca/2014/04/aizu-shintogo-kunimitsu-tanto-kata/ from here it looks like there is still plenty of room inside your hardened area to create a classical tanto kissaki/tip if you decide to: http://islandblacksmith.ca/2014/06/classical-tanto-geometry-blade-kissaki-tip/ that is a lovely piece of cedar but might be a bit soft for tanto, nootka cypress/alaskan yellow "cedar" is a bit closer to the hardness and workability of hounoki... keep up the journey towards excellence!
  8. @Jan ...nice! next time let me know when you are in town! that was one approach i considered, but there was too much damage to the blade, particularly to the edge for several inches above the machi...so it would have been a suriage wakizashi at most, however there was some other major areas of damage to the shape so i chose the two tanto route to make the most use of the steel...i certainly could have made this tanto a very slender shinogi-zukuri if i had wanted to tackle a shinogi-zukuri polish this summer though... ^______^
  9. @Wes much appreciated...indeed, redemptive art... ^____^
  10. @Wes i just added a "before" photo to the page...the antique blade had lost its hamon (likely damaged by fire) and then was abused, poorly reshaped (polished with a belt sander?), bent, and severely damaged for several inches above the hamachi..this tanto is made from the front half, i may get another tanto out of the rest in the future... so i forged it from shinogi-zukuri to hira-zukuri and forged a tang to maximize use of the steel...delicate work but worth the effort...
  11. @ScottWright i needed to get it done with a deadline along with some other projects so no videos, only a few photos (more on the website)...but a professional crew came by for some footage of the forge and documented the final assembly so it should be part of a video in the future... islandblacksmith.ca/2017/08/komorisan-back-in-the-forge/

  13. A true and accurate understanding of the past is an important step towards a good future. 温故知新 (on ko chi shin) is an expression that most directly translates to, "study the old to know the new". This blade began as a reclaimed piece of a damaged antique sword and was carefully hand forged in a charcoal fire, smoothed with files and a sen scraper, differentially hardened using traditional water quench yaki-ire, and polished by hand with natural Japanese water stones. Materials for the chisagatana style koshirae mounting include Japanese hounoki wood for the handle and scabbard, copper bus bar for the habaki, reclaimed brass from the original mount for the fuchi and kojiri, forged brass kick plate for the kashira and seppa, black lacquered samegawa and kangaroo leather for the tsuka, lacquered steel for the mekugi, buffalo horn for the koiguchi and kurikata, and an iron spike salvaged from thirty feet under the Pacific for the tsuba. The saya is finished with ishime-ji (stone surface) made from natural urushi lacquer and tea leaves, the kurikata was carved from reclaimed horn button rescued from a vintage coat, and the sageo cord comes from an outdoor antique market in Kyoto.

  14. @peter, i have seen similar methods of soldering used by traditional copper vessel makers in japan... thanks, @peter!
