But...how does it shave?
edit: @ DPflaumer: Hello
I don't know, but it might be a little tricky for those hard to reach places, like under the nose.
Also, hi fellow resident of Indiana
That is like asking "Is your car a good jetski?"
The reason why he cut through the phone book was because he didn't have 30 degrees of angle. Rookie!
The reason he can get away with that kind of manuever is because katanas have an appleseed convex geometry to the blade. If you're unfamiliar with that, imagine a V where the edge is and then just imagine it as a bit fatter and you have a convex edge (but most of you already know that). Also, there are no secondary bevels on a good katana, they one have a single bevel coming from the rear of the blade...not a second like a pocket knife. These geometric advances are what give the katana its ability...after that cut to the phonebook, it may have only needed what we call a touchup.
our full hollow Sheffield and Solingen wonders would be absolutely destroyed if we tried that. :)
I never understood the slicing through paper demonstrations, pretty much any blade coming off a 1k stone can do that. None of that other stuff was that impressive either, not when you think about the actual physics and the amount of energy in the blade as it is moving.
The only test that counts is the shave test. Now, if he had gotten a BBS from that big blade........
Not so much so in my opinion. Even dull kitchen knifes can pass the paper shredding test. When they FALL STRAIGHT down and through without rolling out like that and without any force, they're sharp (like razors probably do, though the wide hilt may cause them to roll, with knives/swords/etc where there is a less definite wedge shape, this doesn't happen). This is sharp for a sword of course, but it's nowhere near as sharp as a razor, because quite frankly if it were, it WOULDN'T hold up to that kind of treatment. Even the hardest materials on earth when edged as narrow as a low angle edge kitchen knife or razor will have their edge ruined by applying the amount of force that these swords edges take.
Knife edge and hollow ground (what I'm assuming razors are), are always much much sharper than the kind of edge combat knives and swords take, because they aren't expected to hold up to this sort of use.
looks good, but when this thing needs sharpening and polishing, if its the real deal its gonna cost
