@@g-bruk8887 about 200 dollars American, if 200 dollars will keep disposable safety razors made of plastic out of the landfills then it’s well worth the price. The problem in America is young men here grow up with safety razors and are entirely unfamiliar with straight razors for the last 100 years. So there would be the teaching curve of learning the old way to shave again. But well worth the cost.
As a barber 43 years, I have to say Japanese shears, razors and steel implements are by far the best in the world. I've tried all kinds. The Japanese beat German Solingen steel in the 80's by a mile and never looked back. All my steel tools are Japanese. Thank you. They literally become extensions of my hands.

Simply not true, technology could definitely be developed to make these just as good and far more efficiently - but there is an inherently human joy in hard work and skill development, and that’s why people appreciate things like this.
Most impressive! As an American, our mass production really undermines the craftsmanship required in ages past. It's so easy to just go to the store and buy a "razor", but once I saw the labor, skill, and time involved in this video, it gives me a much greater appreciation for the small things I usually take for granted. If only everything in life took this discipline to master, I feel people would appreciate the little things that much more. Always a fan of a tradesmen taking pride in their work. The everyday "Mundane" has much more depth, sweat, and passion than we'll ever truly comprehend.
Considering the $400 and up cost for the razor plus the required items to get it sharp plus the shave soap and shave brush I've learned to appreciate Bic single blade disposables. Actually I shave with a mass produced straight razor. It's a better shave than anything else I've used. You mentioned appreciation. If I hade a razor from a blade smith like the gentleman in the video I would love getting up in the morning and might like the man in the mirror more than I usually do.
@@bozzskaggs112 To be fair, you can buy a good razor for $200 and have it honed for less than $50 plus a few ancillaries for another $50, and you never have to spend that $200 again. In the long run, the long run mind you, a good straight razor will save a lot of money over a cartridge razor. If you are patient, you can buy a really good used one off fleabay for $25 delivered, and save $175 off the above prices. But, each to their own. As long as you're getting a shave that's sufficient for your purposes, that's all that matters.
When i saw the final test..damn! Thats sharp! Hope the trainee could further grow the business. People now does not know that old school razors are mor3 economical than disposable ones..you can just buy one in your lifetime and just sharpen it with a leather belt. Cheers from philippines! Japanese techniques in manufacturing is always amazing!
É um trabalho metódico, e de extrema paciência. Requer fazer um produto em série com o mesmo padrão de tamanho e qualidade. Forjar o ferro no fogo para moldá-lo ainda serve para filosofarmos um pouco sobre nós mesmos, quão duros e brutos somos até a perfeição do corte. E, por fim, os artesãos trabalham concorrendo com uma produção esmagadora de barbeadores, ainda assim, confiam no produto que fabricam, e sabem que têm um espaço garantido no mercado das lâminas. Parabéns aos artesãos pelo trabalho de alta qualidade que leva a marca japonesa. Abraço cordial. Salve Maria!.

Fantastic. Very good work. I was curious about the brown and black pasta that passed to do the heat treatment. I have been interested in this pasta for a long time to make my work on my knives easier. Please, can you teach me how to make this pasta? Thank you very much
“Paste” is the word you’re looking for. Pasta is spaghetti. It is made from clay. My understanding is most smiths make it themselves but there are commercial suppliers. Companies that sell knife making supplies would be the logical place to start.

Me ha fascinado el arte que tienen los japoneses fabricando las Kamisoris, eso no tiene precedentes. Creo que son los que fabrican con el mejor acero del mundo y han descartados al acero alemán, una pena que nuestro acero fue precisamente muy reconocido por los japoneses y dejaran de fabricar nuestras prestigiosas Filarmónicas.

Une vidéo très intéressante et instructive. Je me demande toujours pourquoi les artisans japonais travaillent encore à plus de 80 ans. N'ont-ils pas droit à une retraite ? Est-ce pour pouvoir transmettre leur métier à des jeunes ?
Love the whole process. How long from start to finish for one razor? How many do they make in a day? These must cost a fortune in order for both of them to make a living. Well worth it I'm sure.
How cool would it be to be there and watch these people weave their crafts. It would be fascinating. The sounds and smells have a beer with the lads after work. Super cool.
Most stainless won't get sharp enough or hold an edge. This blade is a combination of two steels, one that is hard to get sharp and hold an edge and one to form the handle and backing.
