I agree 100%. Most TH-cam video producer know nothing about documentary film production. Not only this guy butchered the video but he also butchered Mr Kato work. I put up with that annoying music and at the end Mr Kato work was not presented.
See how Mr. Kiyoshi cuts and scrap the edges like carrots!! Isn't? Wonderfull to watch and get inspiration. I now realize what knives are all about and what is put into making a knife like this. Thanking you for posting on the net.
Arctic Circle Hopefully he has somebody to pass his craft down to. He is a true artist there are people who take a rasp and put it to a grinder and put a handful on it and call it a knife.
+raccoonradar DUDE! Seriously! like WTHeck just went on there? Maybe i missed something because i was mesmerized but did he use a friggin draw knife, to cut hardened steel? if so, this guy's not a craftsman, he's a ****in wizzard.
It is similar to a draw knife in design, but has a insanely hard edge. It functions like a engraving chisel in how it cuts, but with the general design of a draw knife to make using it easier. Hope I could be of assistance!
What an amazing process to watch this master at work. he has such a determined yet subtle look in his face. the quality of his craftsmanship come thru with the brilliance of his final product.
What beautiful craftsmanship and labor. I was misgiving about a 300+ Dollars Deba or Yanagiba but after seeing this i want a Yanagiba forged like that knife he made.
Full respect for your work art and skill sir...!! This is why japanese blades are very expensive to buy.. Love to have one of these blades which is made by you... Love from India
Very AWESOME!! The music turns it into a spiritual event. A very talented and gifted man. Thank you for posting this wonderful video. I knew that there was a reason why I always preferred Japanese knives and blades. SuperSniperSal USMC Disabled Vet
thankyou so much for sharing this. what a wonderful man and so much love has gone in to knife making a true master. i wonder does he ever make katana swords anymore for private collectors. his skill is truly amazing i could sit and watch him for days. i hope some day to goto japan and see this true art happen in front of me. just stunning craftsmanship. for all that hard work at his age i really hope he gets every penny for that he rightfully deserves. such a privilege to see this. thanks
This guy is a PURE ARTIST! I could watch him blacksmith all day. After he tempers the blades...other than thinning the knife - why does he hammer on cold metal. I need that metal planner...
I've been making knives for several years now and watching this video was interesting, but I have to say I was most impressed at the 11:35 mark. All that would take is one bad motion and that whole knife would be junk. Don't get me wrong, this entire process is impressive, but using a draw knife to rough in a uniform cutting geometry is nuts.
Not sure if this was intentional but this video along with the music selection is strangely reminscent of the Kill Bill movie, particularly the scene where the swordmaker makes the main character her blade. Search Hattori Hanzo sword scene to have a look.
Great video, does he still make knives? How many do you get each month / year, please? And what about his apprentice, Mazaki (?): does he follows all the steps Sato San uses to make all his knives as well? Sure do hope so...
And some Chelsea Miller from Brooklyn asks 800 dollars for her "custom made chef knife" grinded of old horse rasps and rotten wood from her family farm !
+entropy11-- In Japan, that tool is called a "sen". He actually wasn't using it on hardened steel. You can see in the beginning of the video that he made a 3 layer steel laminate called, "san mai" by forge welding a high carbon steel core (for the edge which ends up in the center) inbetween 2 pieces of mild steel, one for each side. The mild steel on the outside doesn't harden during the quench due to it's low carbon content, which allows the bladesmith to use the "sen" (made from hardened high carbon steel) after the hardening process to scrape away the soft steel on the sides to expose the hardened center (edge) steel. If you think about it, a sen cuts kind of like a file does, but it's only cutting with one sharp edge as opposed to the many edges (teeth) on a file. I believe the sen makes faster work of the initial stock reduction to expose the cutting edge (by tapering down in thickness from spine to edge), whereas a file will leave a flatter, more consistant finish and clean up the marks left from using the sen. This all sets the initial blade geometry, which is then refined even further by using a number of different water stones, starting with coarser ones and working up through finer and finer ones, just like when using sandpaper. Something along those lines at least. ;-) Hope that makes sense! :)
Maksim, thank you for posting this video, it is exceptional. The few slow motion sequences revealed subtle details in his process. The next day after the annealing (or normalizing, depending) he cold forged a curve in the blade, both directions. I'm assuming this was a grain structure refinement step but I would sure like to know what he says. Did he explain this step to you? Did he have a name for this step? Thanks Robert
back again wondering what the clay he uses is. when I use clay it usually cemets to the knife and wont come off unless I scrape it off along with the forge scale finish. hmm...more research needed.
A couple questions Maksim. The very purpose of cold forging prior to the hardening has eluded many American smiths, which includes myself. For what reason is Kato cold forging? I suspected since he annealed and then cold forged, he was fracturing the crystalline structure evenly similar to a normalizing cycle, which he didn't do in general sense. If this is not the reason then why? Otherwise once he brought the blade up to temp. for hardening, any other reason to have the grains fractured is nullified by the grain reset. Please correct me if I am wrong. Also, is this a San-Mai construction? It is hard to tell when he is drawing out the tang on the power hammer, and not sure if the scale is tricking my eye, but I am counting 4 layers. As if the initial long bar stock was mild steel with two pieces of high carbon stacked on top of that and another piece of mild on top of all of those. EDIT: As I watch again, it looks like a 3 bar construction with the long bar stock being mild with one piece of high carbon on top of that along with a mild steel bar on top of that. Thanks for your time and posting this video. Makes me want to buy a Kato blade sooner rather than later.
Daniel C as far as I can tell, it's a kasumiyaki blade design. One side mild steel/iron, the other side is high carbon steel. The urasaki would take most of the high carbon steel, leaving only a little bit on the edge, and the back of the knife to keep the layer together. A downside to these knives is after 40 or so years, it will tend to warp if made by someone who isn't a master bladesmith. The warping occurs as the two metals stretch and contract differently over time. I hope I could be of assistance!
It's a san-mai. You can see it when he does the forge welding at around 1:10 - Long bar of mild steel on the bottom, high carbon steel in the middle (you see him flux both sides of it), then another mild steel on top (fluxed on one side only).
still dont understand whats going on there he anneals the blades, to remove stress then he cold forges them which introduces stress and then quenches them without annealing. ive seen a lot of japanese smiths do this, i dont know why...hmm more research needed
Учитывая тот факт что японской школе изготовления холодного оружия не одна сотня лет, делаю предположение, что многие мастера и сами не знают зачем делают ту или иную операцию. Их просто так научили и всё. И никто уже не вспомнит что 780 лет назад старый старый мастер просто ошибся в чем то при изготовлении очередного шедевра, а на следующий день умер. Ученики же старательно повторяют данную операцию до сих пор.
Japanese sword and knife making is truly amazing. I never get tired of watching these masters at work and displaying their art.
I could sit and watch this man work for years. lol What an inspiration of craftsmanship.
Same but this shitty music makes me want to kill my self. :D
I have never seen someone peeling metal like that before, really amazing.
Its been 5 years. Has anything changed? Or is this still the only knife peeling you have witnessed?

It's too bad such a gorgeous video has music playing the whole time... it was unnecessary. The sounds of the fire and hammer would have been enough.

Supreme extremely knife making ever seen before!
I've never seen a wood planer-like tool used on hardened steel before.

***** It is for scale removal

From what I've read cold forging before austenizing can allow for a slight finer grain when up to austenizing temperature
11:50 holy cow that thing must be sharp and hardened ad nauseum.
Yes its called a Sen
still dont understand whats going on there

then he cold forges them which introduces stress and then quenches them without annealing.
