About This Project

About This Project

Japanese swords represent premium quality and sharpness worldwide. Traditional Japanese craftsmanship realizes the utmost excellence. The same traditions bring greatness to the Panasonic shaver.
Our challenge was to use this outstanding craftsmanship to forge a Japanese sword from Panasonic shaver steel. Shaver blade stainless steel is extremely hard and difficult to fabricate. Our traditional swordsmith faced a surmountable challenge.

SHARPNESS OF PANASONIC SWORD PUT TO THE TEST

Excellent Cutting!

Iaijutsu is a combative quick-draw sword technique that involves rapidly removing a Japanese sword
from its scabbard in a single fluid movement and striking an opponent. Isao Machii, an Iaijutsu master,
used Panasonic's sword to cut a variety of objects.

Yuya Nakanishi

"At first, I was a little concerned about how to make a sword with the thin stainless steel plates I was given. After a lot of hard work involving thorough temperature control and plenty of patience, I finally completed the sword and thought, 'Done at last!' Nevertheless, dealing with a new steel material was fun. I shave with Panasonic shaver blades like everyone else, but as a swordsmith, I was surprised to see such technology packed into something so small."


Yuya Nakanishi was born in 1984 and was attracted to the mysterious beauty of Japanese swords as a teenager. Yuya Nakanishi became determined to become a swordsmith and began his seven years of training when he was 20. Yuya Nakanishi established his own workshop nestled in the picturesque mountains of Kyoto Prefecture in October 2014. His devotion to the practicality, spirituality, and art lives in the craftsmanship of Japanese swords.

Isao Machii

"My first impression holding this sword was its lightness. This could be because of the sword's center of gravity or the uniformity of the metal. The wonderful balance makes the Japanese sword easy-to-wield. It's also pretty sharp and can even cut a cooper rod in half. The sword doesn't rust, so it's maintenance-free. I'd really like to have one myself."


Isao Machii was born in 1973. He became well versed in martial arts in his childhood, learning kendo at the age of seven with affinity for spearmanship using pole weapons and Japanese archery. Isao Machii teaches Iaijutsu at the Shushinkan while diligently continuing his training every day to prefect his own skill. Isao Machii has earned international acclaim as an Iaijutsu master with six Guinness World Records:
(1) Fastest 1,000 martial arts sword cuts (36 min, 4 sec) (2) Most martial arts katana cuts to one mat (8) (3) Most sword cuts to straw mats in three minutes (252) (4) Fastest tennis ball (820 km/h) cut by sword (5) Cutting a 6 mm BB gun pellet with a sword (350 km/hour) (6) Most sword cuts to straw mats in one minute (87)
