Bladed weapons have been around for thousands of years. They are proven to still be useful in the modern day by folks in the military and regular life that protect themselves with them. While they are not commonly used, battle ready katanas have to be of high quality to get that title. They have to pass the cutting test, called the Tameshigiri. They are also known as functional katanas. That means that these are not items one has for decoration, but for use in real world situations. While the time may never come that someone will need a sword, it is always good to have a practical back up.
Everyday Use
While most people think they need only limited instruction in bladed weapons, battle ready katanas are not the sort to have that mindset. The person who owns one should understand it to the point that it becomes an extension. A person needs to understand how to use all the blade. They should learn to become confident when they strike. Most who have not practiced can end up either shattering the blade or getting it stuck. That means that someone should practice daily with a katana. That means a show of dedication.
Buy Quality
For a weapon, like battle ready katanas, to be considered battle ready means they must be of a certain quality. They need to have high enough quality steel that they keep and edge the full length of the tang. A person needs to understand balance in a weapon. Balance can mean the difference in a swing of the sword or an easily blocked blunder. The weapon needs to not have all the decorations that a show blade has.
