Katana vs Broadsword...test cutting- National Geographic

Aleksey G. · 22nd September 2009, 01:19 PM

Man, sucks video cuts it of at the end like that....
... The european guy overcommits on some strikes I think, his shoulder is all up front and does noit stop the sword in time if he needs to counter strike.

I was always fascinated by counter testing edged weapons from different cultures in battle, is there a better sword out there if the skill of both opponents is "generally" equal? Better design, strength, rigidity etc..
If you look on the tube, there are videos of katana vs the jian fights, rapier vs the broad sword etc....
I dont see much of the middle eastern curved sabers though...(shamshirs, kilijs etc...), thats upsetting, would like to see some field testing and techniques with that.

While I guess the actual tests themselves might be nice to show if one encounters someone who, for some reason, have gotten the notion that Europeans words are poor cutters, the program it's all taken from seems to have some severe issues though. "The broadsword relies of brute strength"?

I'm also rather sceptical about the whole "x vs y" concept. I don't think I've ever seen anyone propose a scenario/testing setup which manages even partially to eliminate the majority of other factors, without simultaneously being far too narrow in scope to say anything about the performance of the swords in general.

There tends to be some favoritism going on in these tests...

often in favor of the nihonto...

it is like when Greyhounds are shown to be faster than Cheetahs oftentimes, but people like the idea of the Cheetah, untamed and fast as hell. But Greyhounds can be just as fast if not faster.

Like-wise people seem to hype up the Katana and say it will cut with ridiculous ease, etc... a sharp European broadsword could too...

and I agree, Middle Eastern and Indian swords are also often ignored. It seems that often it is the Chinese, Japanese, and European swords that people are concerned with... Where are the archipelago blades? The dha/darb? The shamshirs and khandas? The saif and the toukuba?

Various 'cut' testing has concluded that it is not just the sharpness, or angle that the blade is sharpened , but the 'polish' of the blade that affects cutting performance.

A highly polished blade has less drag as it slices and aids cutting ability. A characteristic of katana blades.

It does not make sense to compare a Katana to a Broadsword. Broadswords were heavier and generally designed to fight against heavily armoured opponents. The katana was not.

It's too bad Albion sword videos of the testing with their traditional blades. The videos I remember showed something you can't do with a katana: cutting the mat on an upward diagonal, using the back edge. The demonstrator did that not only with a replica arming sword, but also with a gladius, and in both cases, he did it one handed. Granted the guy was a smith with Conan-style arms, but it was still an interesting demonstration. The Cold Steel videos show similar results.

Bottom line is that a well made western blade (i.e. Albion) cuts at least as well as a katana, and a heavy Chinese dao can cut even better (if you believe Cold Steel). If you use a single demonstrator who is familiar with all the blades and test cuts them all against the same type of target, the katana shows little if any superiority. IMHO, the katana really shines when you have Mr. black-belt kendoka demonstrating against Mr. Joe Average reenactor.

Best,

Ah kronckew, I expected you to come in and elaborate on that.

I have read that before too, very cool.

Perhaps versatility is something not often tested for? I feel as though all weapons have been developed for the type of warfare encountered or practiced by those cultures... the "soft" iron swords of the Celts was perfectly acceptable at the time considering the warfare and technology but would be near-useless for a Spanish foot soldier in the 14th century.

So true.

kronckew · 22nd September 2009, 08:21 PM

blade cross section variations could also affect cutting, wide fullers possibly can cut down friction drag while cutting soft materials, as do the cutouts and odd blade geometries of cheese knives.

and now, a diversion.

...

there was a race between a professionally jockeyed race horse and a retired (and thus off peak training) greyhound over two furlongs (1/4 mile), the greyhound won by two horse lengths. similarly, top gear had a race between a class A racing greyhound (worth about £20000) against a sports car over two laps. the grey won by several seconds.

coincidentally that track was the one in ireland where my millie used to race in her early career in dublin. after moving to the UK, she handily won a stakes race, looking up the time and distance, she ran an average of 34 mph over 550 yards. a greyhounds top speed is usually noted at around 45 mph.

they figure they reach top speed in about 2 strides out of the trap, a feat millie was noted for. she normally lead from the front when she won and placed in the money over 2/3 of her 80 races before she was fouled by another dog and injured enough she was retired & thus went home with me and blue, my other greyhound. he never raced, but is a fiend on rabbits and other small animals like foxes & muntjaq deer. (he doesn't catch them but has great fun chasing them)

anyhow, there was a study recently where they were doing motion studies on the spines of greyhounds and cheetahs to see how they used their flex to store and release energy. the greyhounds consistently tested faster over the runs they were using. they put it down to motivation. greys like to run, cheetahs apparently only do it because they have to.

the 70mph top speed for a cheetah was apparently taken from a guesstimate made in africa over a rough terrain with a manual stopwatch, so is suspect.

a greyhound track owner did import a few cheetahs in the early part of the 20th century, trained them over a few months and then raced one against greyhounds to which they'd been accustomed to each other so as to not try to kill each other. anyway there was one race, the cheetah won handily, but was never raced again. appears cheetahs run out of steam very fast and take longer to recharge.

we now return you to our regularly scheduled thread.

i'm rather fond of the cold steel series of cutting tests of their swords, the one on their version of the dutch klewang is one of my favourites as i have a proper original dutch one myself. their use of pig carcasses complete with bones is a close as we are likely to get to real.

Cutlass cutting test

there are a number of cutting tests with swords on youtube, here's one of the hanwei dao (another one i have) vs. bamboo.

Back to cutting; I cut with a Piso Podang occasionally; it has a nicely curved blade .
The test material is a Pool Noodle stuck upright in a base; the noodles offer very little resistance so the cutting technique is everything .

Took me quite a bit of practice to get a nice cut as you have to draw the blade through the cut; otherwise the noodle just deflects .

Gotta say that I believe that at least half of the Katana's reputation is hype.

IMHO (and I've only owned a few, but always enjoyed tesing them on bamboo and rolled mats) Japanese swords are rather beautiful, interesting pieces of art.

But in the great scheme of weapons evolution, little more than eccentic foibles.

I'm not going to argue that the Katana's level of 'sharpness' is going to be hard to match, but as for 'combat worthiness' or pretty much any other measure, it's (for me) just a non-starter.

A good european sword is so much more fit for purpose (Why the hell did they choose a broadsword for comparison, so all but the most ill-imformed viewer would recognise it?).

But hey, lets start with the basics.

How many man-hours does it take to 'create' a good Katana?
How many 'good' broadswords could be created in the same timeframe?
Katana Vs unarmed peasant/bound POW/Criminal etc = Excellent
Katana Vs light armour (leather/fabric/thin laminated wood/V thin metal) = Medium results.
Katana Vs Medium/heavy armour = potential catestrophic damage to blade, as does any even glancing blow to solid object etc.

European sword on the other hand.......
Hack and freaking slay all day then (potentially) bang the kinks out with a lump hammer and sharpen to a good and bloody lethal ragged edge with some random smooth rock from a stream!

Well, how long does it take to make a katana, if you're just aiming for a good weapon (and not an "art sword")? How long does a 15th century arming sword take to make? Looking at the cost of making modern day replicas I guess a katana might take slightly longer, but without any numbers for comparison it seems meaningless to try and guess if the difference is meaningful or not.

The armour bit seems odd as well. The Japanese did have iron armour after all, so it seems decidedly odd that they'd stick to a sword which risked catastrophic failure if you accidentally hit your opponents armour. And even without armour I find such a sword an oddity, given that you might always happen to hit your opponents sword, coin purse teeth, some buckle or jewellery, etc. (This isn't to say that I believe the Japanese would simply try to cut through iron lamellar. As far as I've understood it, both in Japan and in Europe, the primary answer to iron armour was to attack where the armour wasn't.)

As for my own experiences, modern ZNKR iaido and kendo kata both avoid edge-on-edge contact (from what I've understood, European longsword fencing does the same), but there's a number of blade-on-blade techniques, some done with a decent amount of force behind them. And for what it's worth, some test cutting I've done with a cheap, modern, Chinese replica has resulted in a few more-than-glancing blows hitting the unyielding chopping block, without the blade cracking. Not traditionally made of course, but even with the improvements in metallurgy over the year it seems to me that a budget offering from China wouldn't be all that good compared to the real thing.

So while there are indeed some who will exaggerate the performance of the katana, I don't feel that the answer to that is to exaggerate in the other direction (such as some of these points may be, or like the last paragraph you wrote about the European blade). Sadly, such often seems to happen when any comparisons are made between sword A and sword B, and it's one reason why I'm sceptical about the possible usefulness of such.
