DIY - How to sharpen a Katana

[@WhiteWeasel93TT]

Your sword came out extremely sharp and people still criticize your method. You you obviously made your method and people don't like to be wrong. Good for you man.

Yes, I appreciate and disappointed with this world for that

[@andthorn3145]

For starters, this is a video on HOW to SHARPEN a katana with HOUSEHOLD ITEMS, not traditional japanese whetstones carved from the ass of the sacred gorund of Mt. Fujji. Hey man, I can't believe so many people full of shit on the comments. The fact that they fantasize katanas shows they are full of BS. I can tell you have had a lot of practice. That cut at the end was quite impressive. And know your way around mantaining a sword with the tools at hand, which is very important knowledge. I love how people tell you what you should do or not do with your katana, as if it were a legendary Tokugawa heirloom passed down by generations of samurai. A katana, is a sword. a piece of steel. It is a tool. And if people cant get around the idea that a katana is just a tool, then they shouldn't be wielding one. Nice video man, keep it up

[@LucianoSilvaOficial]

Thanks Andres, and if i had mentioned that this sword is made in china they would probably say it's not a sword at all.

[@9thStreetNinja]

Ironically enough, the reason I watched this video is because someone gave me a Wakizashi about 3 and a half years ago. Before this I only owed a "traditional" looking Ninja To that I purchased for 190.00, 25 years ago (turned out to be a wall mount sword). Before that; only a boken. I wrapped the boken handle with cord to give it a realistic feel. Well, two days ago I decided to refurbish the scabbard to the Wakazishi gift I was given a few years ago. It was worn; duct tape held on a shoe lace attached to a broken off wooden cord mount still hanging on due to the shoe lace. Duct tape alsp held on the metal blade guard on the open end of the scabbard. I did not want the aged look of tradition. I wanted duabilty and function implementing modern, light wieght components. I stripped off the duct tape taking what was left of the sheen with it. I stripped off end cap cover as well. I sanded by hand course to ultra fine. I built a paint booth by sweeping, mopping and dusting my ultily room. I then laid out a sheet and set up a mount to hold my scabbard from what I could find in my garage (propane hand held torch with stem). I simply placed the torch under the sheet and cut a 1/4 inch hole for the stem to come through, the slid the scabbard down over the stem where the sword enters in. Before painting the scabbard with corosion proof all weather primer mixed with matt black paint, I drilled two holes in the scabbard to mount an aluminium rope loop above the traditional wooded mount and I mounted this piece running vertical, not horizontal. This is my mount for pack carry. I have cargo loops on the side of my tactical pack that perfectly hold my scabbard on the right side of my pack. I used sex bolts to attach rope loop rather than tiny wood screws that can be jerked out of the wood. I also reattached original cord mount with Gorilla brand super glue. Before I mounted the aluminium rope loop, I painted; 4 coats in 6 hours for ample dry time between coats, dusting the scabbard with paint one layer at a time. I sanded and painted the metal blade guard, used two complete rotatians of electrical tape to compensate for loosness under the metal guard, dotted the inside of the guard with super glue and worked it all the way onto the scabbard; tight enough for tight fit, without tearing into tape on the way down. The end product was so pristine, that it made the furniature covering the tang to look subpar to the scabbard; scabbard looked like a Batman weapon and the handle and tsuba looked like they belonged in something much older or simple looking. The tsuba had been rubbed clean of original finnish and was dusted with tiny rust particals and tarnished. So... I chose to venture into the unknown and break it down and make it new to match the scabbard. Wow!!! Turns out I had been given an exceptional sword; easily a 5 or 6 hundred dollar Wakizashi, battle born, full tang, everything very snug and fit (I am not an expert in handling these sword, nor have I ever worked on them or refurbished one until two days ago, but I have read a good deal of information on them and formed my own opinion as to what makes this weapon/tool/piece of art/object of deep thought and stimuli for inspiration/an extention of one's own being (soul)... Valuable; able to have value; I epressed that in my refurbishing project). I sanded everything to perfection and then painted with love. This sword looks brand new, ready and custom without traditional flare; looks and feels very solid, tactical. Now... I I move on to learning different sharpening meathods. I do have a long sharpening stone that my grandfather left beind. I am thinking I can use the techniques he taught me with 10 and 12 inch knives (his knives were immaculate and scary sharp) and apply that to the Wakazishi. I'm going to watch any videos I can first to pick the brains of those with experience, then proceed with disarmament. So far, I have not seen anyone doing what Grandpa did (I only just started watching these though) in that Grandpa approached the sharpening process like a prayer, or deep meditation. The process was expected to take awhile; might even be broken up over a few sessions, no hurry. To hurry was not the point, we had utility knives on standby for immediate needs. The other knives though; they were special, if only to us; I see that in the Wakizashi. At the end of the day it is a tool forged from elements of creation, what one puts into preserving what has been created speaks truth on all levels. Thank you for you video!

You know, I've owned swords and have been training with them for YEARS AND YEARS, and I have never ONCE thought about using sandpaper and just wetting it like you'd do with a whetstone. That's actually fucking brilliant dude. It's so much cheaper to buy sandpaper and it has the same effect once you wet it with some water. This is a really smart way to sharpen cheaply, especially if it's just a sword that you practice with and not a seriously high end one. And it's super cool how sharp you got it! This video just blew my mind man, great job. 👍🏼

[@MySkobi]

Before everyone critizises... This is an OK video. If you really own a real high quality katana, than you invest in some real wet stones of high granulation. I saw you using only granulation 360... Well I start sharpening my katanas with wetstone 1000 granulation. And than finish with 6000. My katanas are so sharp I can cut with my imagination. But if you use your katanas for show or just to work a certain period of time, than your technique is equaly good. And its a similar technique. So, good job

[@yosefyosef4223]

Can I take a look your katana?

[@KaptainCanuck]

You are obviously misinformed. Only two grits are needed for sharpening and honing: 400 and 1000.

[@KaptainCanuck]

1000/2000 (N. A./Japan) is for a finishing edge/honing only. If there are nicks and chips, start lower and finish at 1000. Over `1000 is polishing grit only.

[@davidcrisp3832]

I ran across this video last week and thought I would give it a go. It was the first time I've ever attempted to sharpen a katana, so I used one of the ones I bought as a wall hanger. Since I don't have this young man's experience, I used painters tape to protect the blade and only left the cutting edge exposed. Even though it was a cheap 1045 Musha, this method put a decent cutting edge on the blade in no time at all. I was so impressed that I went on to put a fine cutting edge on the 1075 Marbles machete I use for camping. After that I took down a stainless steel European wall hanger and put a sharp edge on that in just a few minutes. WOW! This is a fast, easy, and very effective method for putting a keen edge on just about any long blade! I'm so glad I found this video! Now I just need to keep practicing this until I have the confidence to try this on better steel... Thank you so much for the upload!

[@LucianoSilvaOficial]

It's a nice sword but a fucking magnet for annoying people.

[@DynomitePunch]

@@LucianoSilvaOficial definitely, and i mean i get WHY it's so popular, anime and japanese videogames and even japanese misticism, which WAS in fact mysterious up until just the recent era around the 2000s made the sword VERY appealing to americans and westerners, at a time when medieval fantasy was looking the same in every movie you had the japanese, who could write several differents types of fantasy from japanese hisotrical or non historical fiction to something between it and chinese to something like final fantasy where japanese things pop up from time to time, when the japanese make fantasy they incorporate several different cultures half the time from western, asian, to middle eastern, to the point where theirs more variety their than in the west, and only recently has western fantasy and medieval movies and such gotten better like game of thrones, outlaw king, etc, so it's no surprise that the katana has so much support when it's gotten much more screen time and positive enforcement than other legendary blades, not t mention again, the secret ism of how they did their stuff and such for the longest time and their adherence to traditionalism, while i respect it, has done what kung fu did and gave a false sense of "the old ways are the best ways" which is common for humans to believe since we cling to the familiar and ten d to shrink away from things that aren't familiar, like industrialism, i admit when i see a sword smith polish a blade with a belt sander, i get aggravated, mostly cuz i don't have that tool, i have to sand my sword down by hand and their are still places i can't get out of some of my swords because they require grinding to remove such as deep yet smooth to the touch pitting, etc, so theirs a hint of jealousy at new types of doing things cuz their not as readily available or affordable so people tend to get upset, not to mention most humans have a habit of sticking to traditionalism, out of respect and a sense of wanting something spiritual to make sense of the world and forging a katana for the japanese is just as much religious as it is work, so yeah you get people who think the thousand time forged sword is the strongest thing in the world, but i will say, using whetstones can actually have a slightly different effect, but i'm not sure if they hurt the hamon of a katana or not, sorry for being so long winded

[@armaanb392]

People think that using whetstone is necessary, but afterall katana is just a steel, dosent matter if it is normal steel, tungsten or tamahagane, and only japanese swordsmiths can sharp katana with the whetstone and call it official, if anyone else does it... It's just a way to sharp and it's not official.. Its a rule of Japan that, only japanese swordsmiths can do things to katana and call it real.. so as we are not japanese swordsmiths, it's ok to work with whatever we love. Good job and thanks for the video and way of the sharpening👍

[@JETBLACKPRIEST]

This is pretty much how I sharpened my dads wall hanger and it proved a serviceable cutter since the steel was as soft as my morning shit I was able to go straight to 400, only thing I would do differently is to remove the paper that isn't held by the clamps as the looseness of it would cause it to sort of wrap around the edge and start of the bevel and round them off which over time would reduce its cutting performance and put somewhat of a convex secondary bevel on it aswell as overpolish the flat or bo-hi, I plan to do this to the ryujin sword katana I purchased recently when it arrives as one review suggested the sharpness could be better

Do your katanas have a paper cutting flat edge, or does this method maintain the original appleseed edge? This is pretty much what I expected you'd be doing rather than using those absurdly expensive Japanese stones people insist on, but I'm just a little worried about the sanding block having a flat surface. I don't test cut often and my Katana is sort of a mix between a conversation starter and an emergency home defense measure. It currently has a 'battlefield' edge, as in it will not cut paper, but it will go through a bottle if the edge alignment is good. I would like it sharper but have always been worried about spoiling the edge as it has an authentic hamon and geometry

[@LucianoSilvaOficial]

Usually my swords cant cut paper since i keep using them to practice cuts very often. Yet they can cut a Green coconut or bamboo with ease, so they are battlefield ready even not being razor sharp. About using sandpaper, dont worry, you will not remove so much metal by hand work with sandpaper.

If you finished the sanding with auto body sand paper for color coats you could sand it to a mirror finish, like 800, 1200 1500, 1800.

Its a chinese knife sold in Brazil by Nautika. It's called Diutac commander. www.nautikalazer.com.br/faca-diutac---ntk-321080/p

That sounds like your surrounded by dogs.

[@zyadnouh2647]

great job, can you tell us all the grits u used? or rather how much farther would you go than 400

[@LucianoSilvaOficial]

I usually go until #600 but you can go further for a better result and It will also be better If you use more intermediate grits than changing directly from rought to smother sand paper.

[@zyadnouh2647]

So for example should I go 200 - 300 - 400 - 600 - 800 - 1200?

[@zyadnouh2647]

also youre using an up and down motion am I correct?

[@johnturner5380]

I own a circa 1939 officers sword. The edge has been completely removed. Possibly filed off as a condition for entry after wwii into the USA. I know nothing. I would like to restore the edge. It has been suggested that sharpening would result in an untempered edge. What should i do? Any suggestions?

[@LucianoSilvaOficial]

If you use a grinder, belt sander or any tool that heats the blade too much, it will mess with the heat treatment. If this sword is a historical piece, i suggest to leave it as is. I dont believe that there are any benefit that will compensate the risk of damaging this sword.

[@johnturner5380]

@@LucianoSilvaOficial I agree. Nothing that creates heat. I would like to have it sharp

[@LucianoSilvaOficial]

@@johnturner5380then use a file, after you stabilished the edge go for sandpaper from 80 to the thinnest you have available. Check this other video: kzbin.info/www/bejne/rIfWq5KVl555r6c

[@johnturner5380]

@@LucianoSilvaOficial thanks. I also have diamond stones, hard Arkansas. I am full of trepidation. Thanks for the encouragement. I haven't removed the hardware. Am interested to see the tang markings. Do you have any thoughts of circa 39 officer's sword vs katana?

[@wolfycssnipereye417]

This method worked really well!! 💜 My Katana is even sharper then when i bought it!

[@nicolas_hang3555]

When ur hammering the pegs back in will they stay or will they fall out

[@bananasquad5516]

No a little more loose each time but they won't just fall out

[@jackal1743]

Hey, do you pass the sword along flat/flush or do you angle the blade?

[@LucianoSilvaOficial]

Flat, keeping the geometry.

[@robertsalomonsanchez]

Good video man, simple is always best

[@LucianoSilvaOficial]

Thank you!

[@anddrewsarracino5371]

How about if you can't get the pegs?

[@LucianoSilvaOficial]

You still can sharpen the Blade but take care to dont let water and dust get in the handle.

[@anddrewsarracino5371]

@LucianoSilvaOficial thanks, can't believe I actually own one now.

[@bassboostedforlife1151]

Omg dude thats was fucking amazing ur really good at what u do keep it up!!! What was the last sandpaper u used to polish it? with

[@LucianoSilvaOficial]

I don,t remember but probably it was #400 or #600. If you go further you can polish the blade but at that point its already cutting very well.

[@jamesmiller9823]

When you sharpen your katana blades do you make them have a convex or concave profile ?

[@LucianoSilvaOficial]

I keep the original profile.

[@jamesmiller9823]

@@LucianoSilvaOficial Thanks for your reply , some people don't know how to properly sharpen a katana, it should be done with a convex edge , others think it should be sharpend with a concave edge "hollow grind " which isn't how you sharpen a katana , but for a knife made for fine cutting , but the edge will chip easily if you cut harder things with it.

[@koibito25]

Why didn't I think about this, you are simply genius

I can finally sharp my great grandfather Arabian sword The sword by which he protected other religion and muslims too.. Thanks alot .

Wow, that is really sharp! Well done! Buddy of mine might be getting a few Katanas soon, said he would like to give me one. I'm definitely gonna use your method if it works out, thanks.

[@kingcandy1984]

Nice I like ur dedication for sharping ur katana and knives

[@forestdweller5581]

Nice job! Think i will try this. I was thinking of using an abrasive liquid cleaning substance such as Cif(aka Jif, Vim, Viss) because it is basically like a very very fine wet sandpaper. But i'm too worried about the chemical interaction with the steel.

[@LucianoSilvaOficial]

Test on another piece of steel before.

[@forestdweller5581]

@@LucianoSilvaOficial Yes indeed. I have used it more to polish other steel tools i make and they turn out really smooth. So it's definitely a fine touch. Works great for cleaning up your kitchen too haha :)

[@cheapmovies25]

I've used flitz for years and it produces a nice satin finish over time

[@jacksonhatfield36]

Very helpful thank you

[@Really2u]

Great video. Nice detail. My question is the tip. When you did the tip. Did you go into the side and take off metal? Or was that just the polished tip I saw at the end? I don't want to thin out my tip. Not saying you may have done something wrong. Trying to learn. As my experience with other blades has taught me. Only sharpen the very edge. Polish and oil the rest. Thank you for the video. Always learning.

[@LucianoSilvaOficial]

The tip goes the same way as the rest of the blade.

[@Really2u]

@@LucianoSilvaOficial ok thank you. I just saw it differently. Thank you for your response. Thank you for your great information. Always learning. Once you stop doing that you are dead. Keep up the great work. 😁

[@BigRedLeg]

dude its just like wet sanding a car. super neat idea. my old mechanic teacher would approve

[@exia7777]

So my katana has a slight ding in it but I'm not sure what to do about it cuz I'm afraid if i sharpen it I'll mess up the wavy lookin pattern on the sword i forgot the name of that lol

[@trumpetwizard7250]

If it's the hamon you're talking about, it goes the whole way through the sword so you won't remove it by sharpening

[@memelordhiram2887]

When do you know when to stop using a certain sandpaper

[@LucianoSilvaOficial]

When you removed all the scratches from the previous abrasive its time to change. You may use diferent angles to notice better when you reach this point.

[@memelordhiram2887]

Oh thanks👍

[@liveretroarcade4819]

When the blade starts to become more mirror like and markless

Tysm i’m gonna pray this works when I buy my katana 🙏🏾

[@fransthefox9682]

Wow. This comment section is full of weeaboos who think they know more about katanas than you, just because they watched anime. LOL A weeaboo can never get his hands on a real katana. However, a person who actually knows things and can separate fact from fiction, CAN get a real katana.

[@LucianoSilvaOficial]

People who believe at the same time that Katanas can cut anything it touches and never get dull but cant handle some "rough" disassembly.

[@fransthefox9682]

Luciano Silva And they show anime and video games as "proof".

[@fransthefox9682]

Luciano Silva Also, you forgot that they pretty much contradict themselves by saying the katana can cut anything. Then why do katana fail to cut open the scabbard when you sheath/unsheath it? XD

[@fransthefox9682]

Low-Class Saiyan I'm talking about those who say it's a disrespectful way to disassemble a katana because they are "holy sacred divine artifacts" or whatever.

[@fransthefox9682]

Low-Class Saiyan Actually, whetstone is for sharpening and polishing. The disassemble happens by removing the bamboo pegs, then the handle. Child's play.

[@Jay-um6eq]

gonna try this, I bought a relatively cheap sword with a brushed Hamon, i reckon this method should deal with it pretty quick

[@HqualH]

Did it work? I bought a dead one for cheap so it’s not sharp and I want to know if it’s worth my time

[@Jay-um6eq]

@@HqualH i actually ended up buying a cheap whetstone and it removed the hamon and sharpened it a fair amount, if i spent longer on it i could get it sharper, sand paper will work exactly the same just depends on the grit
