Sword cuts bullet

No magic here.

A bullet is relatively soft, and if fired perfectly into any edge--even some butter knives--it'll fragment easily. Factor in, as well, the comparatively low velocity of a handgun.

This isn't so much a celebration of the katana, but the reality of a bullet's construction.

There's a second video of some soldiers firing a .50 BMG into a katana. The sword is shattered by the heavier, more erratic trajectories of multiple rounds.

I would wager if you fired a 9mm into the side of a katana blade, the bullet would cause significant damage to the sword, since the energy of the bullet hits a flat surface.
 
Watchful is right hewre, have you ever seen how much a bullet morphs when it hits a person? They become like butter, It wouldnt surprise me in the least bit if they had the black of a steakknife up there and it did the same thing. The force combined with the soft bullet metal simple pulls the bullet apart. When I see either someone who can actually slice rounds while moving or a sword that could cut the stationary gun in half, Ill be surprised.
 
Its interesting but I agree with the others.

Handgun bullets are soft, made of lead and/or copper. Some handgun bullets are made to deform on impact, such as hollow points.

I do a fair amount of handgun shooting. I go to the range 3-4 times a month and shoot 800-1000 rounds a month. That gun is a 1911 type, looks like a .45 caliber. It looks like the round is a lead round nose or a full metal copper jacket type of bullet.
 
Long ago and far away I belonged to a muzzle loading rifle club. We used to split balls on ax and knife blades all the time. It is not difficult and the pure lead bullets do no damage to the edge. A typical .45ACP bullet is going about 830 fps. (faster or slower depending on the load.) Our rifles were shooting close to 2000 fps.

There is an awful lot of hype about Japanese swords. I have been told that the cut .50 BMG barrels in two without damaging the edge. :jerkit: I would sure like to see that.

It's true you've heard this--I don't dispute it.

But you won't find any footage of this act, because there isn't any. Search all you like--the evidence isn't out there. This is a classic "urban legend" of Japanese swordsmanship, and the more you think about it plainly, the less possible it becomes.

You would heavily damage the .50 barrel, that's for sure. But the weapon would probably still safely fire--whereas the sword would be trashed.

Think of it this way: you couldn't chop an M2 barrel with an axe, could you? How then could a sword--with half the mass and virtually no chopping edge--do better? A sword can out-slice an axe, but it can't out-chop one.

I don't dispute someone has tried this, somewhere...but the results were "contra-positive," and any footage was chucked in the ash can.
 
I have heard that legend also.I thought about it,and was wondering if it could be possible, if the barrel had been over heated enough from firing to cause it to soften?
 
A rapidly heated barrel merely softens *slightly*. The main reason you change the barrel in a hot weapon is to correct "droop," in which your bullets start strafing the ground in a target.

A hot barrel, even with droop, is still a pretty hard thing. You would likely cause a little more damage with the sword on the outside of the barrel, but again, you'd bend the heck out of the sword if not take chunks out of the edge.
