Yes, the katana can and must be used with only one hand. It is a two-handed weapon, yet it must be drawn with a single hand at first. The cutting edge (ha) is aligned with the interior of the saya. The thumb softly presses on the guard or tsuba just before the draw begins. This helps keep the sword's weight balanced between your arms.
When drawing your katana for the first time, use your strong side (left if you are right-handed, right if you are left-handed). Once you have drawn your sword, take care not to let it touch the ground; otherwise, you will need to start all over again.
Once you have mastered how to draw your sword, release your grip on the hilt and slide your hand down along the blade until it meets the handle. Now that both your hands are free, you can fight with confidence!
Although this may look like hard work, once you get the hang of it, drawing your sword is a quick and easy process. Just make sure you don't let go of the hilt until after you have pulled it out of its sheath.
Katana swords are two-handed swords. They can be roughly the weight of a longsword. Although they may be used with one hand, the length of the grip and the curve of the blade make handling difficult. It is recommended to wear leather gloves when using this weapon.
Because it is so difficult to use, most people will find some way to adapt it for them. Some techniques require two hands for normal operation, but there are many others that can be done with one. It is all about what kind of technique you are trying to do and how your partner is fighting back. If they have something that can be used as a grappling hook, for example, you can still perform a high sweep even if you only have room for the tip of the sword in your hand.
People have been adapting weapons from different styles of fencing for hundreds of years. There are many ways to use a sword that don't follow any particular pattern or method. It's up to you to figure out how best to exploit your enemy's weaknesses during a fight.
The Katana, like the European longsword, is often a two-handed sword (as European culture was always on the cutting edge of killing each other, they tended to trade gear a lot). Both may be used with one hand, although the leverage is reduced. Initially, the samurai sword would be held in both hands. As they gained experience, they were able to reduce the amount of contact they had with the weapon itself.
In terms of protection, the katana has several advantages over the longsword. The hilt of the katana is designed to absorb some of the force of a blow, reducing the chance of being injured by it. Also, since there's no sharp point, you avoid getting yourself stabbed. Finally, since the blade is usually only about 1/4 inch thick, you don't risk receiving a serious cut from it.
In conclusion, yes, a samurai sword can be used with one hand. However, it is not recommended until you have many years of experience because it reduces your ability to defend yourself.
When drawing the sword, whether a tachi or a katana, you grip the saya with your left hand from beneath, your fingers supporting the mune (opposite side to the cutting edge) and the cutting edge facing upwards, while your right hand grips the tsuka from above, your fingers resting firmly on the cutting edge. You will know which end is which because the tsuka has a ring of ura-eboshi (ruby like stones) attached to it.
Now you pull the sword out in one smooth motion by bending both knees and swinging your body backwards, allowing the blade to come up under your arm and over your head. The tip should be pointing towards the sky as you draw it back into position.
Once drawn, the sword must be held with the giri (firmness) of a stone until needed. It is impossible to maintain enough strength in the hand holding the hilt to properly wield the sword while at the same time trying to strike an opponent. Even when not attacking, the samurai wore his sword and knew that he could bring it up in a moment's notice.
Samurais usually carried two swords. One was their main fighting weapon, used for slashing and stabbing. The other was used for blocking and countering enemy attacks, mostly from knives. Sometimes they would carry three swords. There were many different styles of sword fighting, but all samurais learned how to use whatever weapons were available to them effectively in battle.
In a normal 2-handed, over-head katana stroke, the left hand is the "power" hand, while the right hand controls the sword. When drawing the blade, the left hand is still responsible for moving the "scabbard" out of the way. A katana cannot be drawn with only your right hand. It must be done with both hands.
However, there are techniques called "left-handed cuts" or "left-handed strikes" that can be used with the left hand only. Some examples include a horizontal cut across an opponent's chest, or a downward strike to the head from above. The aim of such techniques is not to deliver a powerful blow, but rather a quick and accurate one. The left-handed strike is used primarily for defensive purposes; it is easier to avoid a punch than a slash from a sharp blade, and thus this type of attack can be used to divert attention away from oneself or another person.
While it is possible to use a left-handed technique, it is usually not as effective as its right-handed counterpart. This is because the left hand is used in holding the sword, which limits what types of moves it can make. Also, the majority of people use their right hands for defense, so they will be ready for anything you throw at them. A skilled swordsman can still manage to inflict serious damage with just their left hand, but it becomes harder to do so repeatedly.
