I am deleting the tumblr apps off my phone but keeping my account. If for some reason you need me to see a .gif of a goat or a clever polyphony pun, feel free to email me at bjjguyphila@gmail.com.
I will still be logging on from time to time from my comp to check up. Hope everyone is having a great weekend!
Cutting of Swords and Armour
In this video is presented a mathematical proof, using confirmed facts from archaeo-metallurgical research and experimental archaeology, that no sword can cut through other swords or plate armour.
Sharpness and hardness of the edge is the least important thing, if iron, copper or bronze should be cut, it is the amount of impact energy which helps the blade to go through cutting medium, by pushing aside the material.
Even if arms & armour are made of soft iron, without carbon and with 2% slag inclusions, the required amount of impact energy is still far beyond human capabilities. That’s why “super steel” capable of “cutting other swords and plate armours” is nothing more than a romantic myth.

“They might try to jew me down on a price.”
-Oklahoma State Rep. Dennis Johnson, on haggling with customers as a small business owner.
“I apologize to the Jews,” Johnson said a minute later, after someone comments on his use of the slur. “They’re good small businessmen as well.”
My name is Frank. I make some slightly less unpleasant noises than I did less than a year ago with a classical guitar. I am often smelly. I heart collar chokes and x-guard sweeps. I am also a geek. I live in South Philly, proud purple belt under Regis Lebre, train with Zak Maxwell and Brian Rago at Gracie Philadelphia. 60% geeky shit, 20% hot girls, 20% jiu-jitsu. May not be safe for work.
