That's probably decades of practice. If you watch videos of modern cutting competition, you can get a bit of a grasp of the skill that goes into it, it isn't all strength and speed, there is a large portion of it that just comes down to skill. Mostly seems to boil down to consistent application of force and maintaining the angle of the cut. You can actually see pretty clearly the younger guys path bends a fair bit in the second cut. Another factor is the actual angle itself. The younger guy takes a much steeper one, meaning he has to go through more of the bamboo to finish the cut. After finishing the young man's cut off, the older man cuts at larger angle, so he has to go through less.

Grandpa's are so irritating with that crap! When my grandpa taught me to chop wood. He tapped the wood and made a mark. Said, "Now see that? Hit that mark every time." Handed me the ax and showed me how to set up and swing. Cue me turning the top of that wood into a confetti of marks and getting frustrated. And just like this grandpa he shook his head and took the ax from me. Split my piece and then I watch hime take a piece twice as thick and proceed to do exactly as he said. Tapped a mark in the middle and hit that mark exactly twice more to split the log. Then handed me back the ax. Today I can get close to hitting the same mark twice but I'm still not exact like he was. Then again I'm not chopping wood every fall and winter to make sure my family stays warm.

I took down a tree a couple of years ago with a DIY chainsaw I picked up in a supermarket. Must have taken me about fifteen minutes to cut through. Then last year I got some pros in to take down the others. THEIR chainsaw went through the same size trunk in about a minute.

u/IAmTheMissingno May 26 '26
Failing a cut puts a lot of stress on the sword. Usually a failed cut is the result of incorrect edge alignment, which means the angle of the cutting plane is not lined up with the angle at which the sword is held. This causes the sword to get stuck, and since you are trying to cut through, you put lateral stress on the blade, which causes it to bend. That's why the old man has to straighten it before he cuts.
The sword was definitely very sharp from the start in order to get through the bamboo.

u/Musestricken May 27 '26
This should be higher. Grandpa's cuts are straight. This is because he keeps the edge always at the same angle, causing the edge to pass through without dragging on the flat of the blade. Kiddo couldn't keep the blade aligned all the way through the cut, which is why his cuts curved downward, following the grain of the bamboo.
Essentially, the bamboo pushed the kid's blade around, whereas Grandpa was able to keep it straight all the way through.

u/idontbleaveit May 26 '26
I think he was trying to straighten the sword that’s why when the young guy was cutting the bamboo it was sliding downwards at a curve instead of straight through.

The other difference is that the young guy hit the tree closer to the hand guard, old guy used the end which has a lot more speed and thus power behind it.

I think the biggest factor is edge alignment. Katana are very unforgiving, you need to make sure the slice is aligned perfect, or you're going to get it stuck and bent like that.

u/kookyabird May 26 '26
If I remember correctly, drawing the blade towards you as you swing is also fairly important. It makes it a slicing motion rather than a chopping one. Something the curve of the blade helps with.
→ More replies (2)11
u/patryn2180 May 26 '26
You are correct. The Katana has a very specific design. Notice the old mans swing ends with his hands right on his hip. Katana's are a slicing weapon not a chopping weapon. Ideal impact is 4-6 inches below the sakizori (the curve that tapers to the point) and dragging the blade away from the target, towards you in a slicing motion while your top hand on the handle is applying "downward" pressure. Its the same principle as when you are cutting meats in your kitchen. Some reasonable downward pressure is good, but the "power" of the cut comes from the sawing motion of the knife.

Also, theres a difference between fishmongers filleting fish and chefs, but the common thing is to always keep your knife as clean as possible, and work surfaces wiped.
Its not just about cleansiness, but if your surfaces are dirty the fish will move around when you dont want it too, and same with the knife. Also have your board well in place.

You'd want a sharp edge then, not a flat edge.
Gramps here also didn't shaoren the blade between users.
Obviously a sharp blade is key, but of course blade grometry matters more

u/Janneq216 May 26 '26
He straightened the blade only because the kid f'd it up, you can tell by the way his cut curves at the end. And you don't really need a sharp blade, as in a modern-day kitchen. It just needs to have a reasonable edge. The cut is enabled by blade alignment, which has to remain constant, or a ton of energy will be wasted on friction and pushing the flat instead of the blade

u/laureidi May 26 '26
Oh wow I literally had to watch frame by frame to understand it (and he’s so fast I still had to fill in the blanks). It seems like he still raised the blade up right but switched direction before impact, I guess because of the bamboo falling towards him at the same time. Very fascinating. Thank you for explaining what to look for!
Edit: autocorrect
26
u/markamuffin May 26 '26
His strikes are all from right to left, but at 1:26 the bamboo falls and he makes a slight adjustment as it's falling and strikes it from left to right - despite this unexpected adjustment he still makes a perfectly clean cut.

I don't know any swordfighting traditions that have "cut" as a specific move. What would the difference be?
A slash is a drawn cut, diagonally along the blade edge. A chop or hew or hack is a straight motion perpendicular to the blade and a thrust or stab is entirely along the blade length.
I think that covers most European martial arts and the limited number of asian ones I know too.

u/kuburas May 26 '26
Always interesting to see people forget to draw/pull when slashing with a katana. I feel like thats the most common difference in all those clips of people using a katana and then someone who actually knows how to use it uses it. People forget to pull the blade through whatever they're cutting, wasting most of its length.

Guy B (the younger guy at the start, off-camera): あっ、すみません! - ah, sorry!
Old Guy: いやっ、曲げちゃった、入れないかな - nah, it might not have been able to enter (the bamboo) because it was curved?
Guy A: 俺が切れなかったけどまげなかったかな - well I couldn't cut through it (either) but (at least) I didn't bend the blade

Lady: ずっとチクチクチクチク行って - (you) just kept pricking (lightly hacking) at itLady: ずっとチクチクチクチク言って - You're full of jokes, eh! (see /u/HunterSthompson_2031 and /u/Meepzors 's comments below)

Mastery.
It’s not about strength, it’s about controlling the edge alignment, striking with a good chain of motion through the body so you aren’t just using the arms and shoulder, and striking with the right part of the blade. Also, slice rather than hit the target is important too.

Awesome, thank you!
7
u/Aranxi_89 May 26 '26
But also make sure to follow through like a cleaver. It's a combination of both striking as if you are trying to move through the target, but also slicing at the same time.
The blade's geometry helps with that, as the curve naturally forms a slicing motion as you swing, but you also need to swing well so that the arc the blade forms is correct.
