Wow, you post one little video of a euro smashing through a katana and everyone gets so defensive! The euro was probably twice the weight of the katana and it's profile geometry is symmetric. What? Did you believe all the posts about katana's that can cut through tanks? Word, +1 from me. Even though im a kat guy, this doesn't surprise me at all, I mean come on just look at the swords they tested, as you said the euro easily out weighed it. It would have been cooler to see a euro of the same weight as the katana or vice versa doing that test.

Wow, you post one little video of a euro smashing through a katana and everyone gets so defensive! It would be the same response if the tables were turned. I'm just really tired of the skewed perception of swords in general. Video like this one And shows like deadliest warrior that have inexperienced sword users that are using swords of sub standard make to the task they are being used for. This goes for most things I have seen euro or otherwise. I have studied many kinds of geometry under different materials and heat treatments. I have broken them down mathemataly and arrow dynamicly. Impact and pressure effect in swords is a are I'm looking at now. The physics of swords is something people overlook to often. Bokken, saya, tsuka and baseball bats are some things I have made that fallow the same physical rules of a sword as far as measurements and material. It took me 100+ hours to make a bokken from African ebony wood. The grain was so tight it exploded in moderate contact. Huge bummer, but was that because I chose the wrong wood for the job? If I posted a video or went on tv would it not be unfair for my bokken to influence major opinion on bokken? It would be bound to happen due to allot of people not knowing the facts. That is what bugs me....

Well yeah cutting that sword with the katana and euro was kinda like fighting a toothpick vs a bokken lol

In the video:
Katana weights 1100g = 2.4 lb Euro weights 1400g = 3.0 lb
The Euro outweights the kat by .6 lb
Personally I don't find that video unrealistic at all - seems real to me. Look closely and you got a light cutter katana vs hard target - and not so light cutter euro vs the same. I do find such one-off study as fruitful as that deadliest warrior show.
Realistically, I know I do have a Hira that could cut through that blade and the table under it, and back up.
Twice.

As mentioned before both blades in the Welt Der Wunder vid that was linked to were made by Stephan Roth, German Master Smith. This means both blades were exceptionally high quality. Both blades did exactly what they were designed to do. A katana is a well designed blade for what it was designed for, but they are not flippen' invincible. Get over it.

I didn't get the guy taking swords away from people by grabbing the blades. Anyone foolish enough to try that with one of my blades would be taking a fast ride to the ER with several fingers in a baggie full of ice

I have broken them down mathemataly and arrow dynamicly. Arrow dynamicly?

Hey ricky, you still selling that last Hira for $300? Oh here's one for the embrace:

I have broken them down mathemataly and arrow dynamicly. Arrow dynamicly? I'm not throwing them through the air. But did do allot of tests on drag with different geometry and blades with and without bo hi. Air resistance does not effect the sword enough for most to notice, but fractions of a second when blades have bulky measures and Bo hi. Also did Polish tests using different viscosity liquid in a slide test. A slide test is holding the blade vertical And seeing how fast it takes Something like a drop of water to slide off. When you hit 10,000 grit and above even water can't cling to the blade. Same result with oils. It proved my theory that high grit symmetrical polishing makes a swords edge last longer because it takes more tries to impart friction on the blade from a target.

How so? Are you polishing the edge? the friction wearing the edge would be determined by the edge and not by any of the rest of the blade, polished or not,wouldn't it? Also, how would this theory hold up to say grinding the edge on a rock or some such? Also, anyone care to guess what would have happened if they had done that test with 2 katana? I would think that the one being swung would end up in the same conditon, if only because the bottom one was held down on a solid object. a long thin object hitting with a small amount of surface area against an object of simmilar hardness that is better braced ie. on a table is going to give more readily than the braced object.more mass to deal with the same force and what not. now why did it break when the euro hit it? That looked to me like he got it in the notch the kat made

Ah right, that one. Look at the longsword, that's not better than windlass quality. Besides that guy had no idea how to use a sword anyway (talk about draw movement, especially with a straight blade).

I think that stupid IDT vid should be labelled "only try this at home if you are an idiot or sick of having all your limbs intact." I would advise no one to ever try that, especially with a sharp sword, anyone notice how she cuts with the mune? I lol'ed

I had been avoiding this thread as the plague it clearly has brought, but I just read the entirety through about 20 minutes ago...and yes, I laughed at the backwards sword. I will be leaving this thread again now.

I find it disturbing that people can actually dislike the video.

That looked to me like he got it in the notch the kat made I feel when people say katana have an "edge" depending on context this is not entirely correct. Swords euro or otherwise cut with the entire blade. The very edge may be sharp, but a blade that is polished to 300 grit won't perform like the blade a 30,000 grit. Even if the very edge is to that level the rest of the sword will get way more Friction and drag even if you don't notice. If a blade is wider and spends less time in the target it just means less Friction And pressure to deform the blade and polish. If I want a hard target I use poplar dowels around 1-2in. Sometimes I wipe blades with oil to further reduce friction. A blade that can cut a target with less disturbing in the target the lower amount of scratch patterns from the target are seen. I have cut a dowel a few times with almost no sign of it on the blade.

Yet another example of a guy who is an actor using poorly designed swords to do a job they were not made for.
