Traditionally, the katana is thrust into the "obi" or sash that holds one's outer garment or "kimono" in place.

Here's the Wiki article... Scroll down to "Men's Obi";

This is a troll. Don't not feed the troll and it will go away.

That is a tough one ask your master...

1st off, i am not studying a katana martial arts, i studied a mix of combat, judo, and karate..

I started became passionate in martial arts a year ago (even though im frail and low on stamina). My sensei admired my eagerness to learn and decided to teach me how to use some weapons. I learned how to weild a nunchuck, arnis (the 2 wooden sticks), a little bit of the long staff, and the katana. My sensei decided to give me his katana because he is going to america soon.

thing is... i didnt recieve a belt holster. i have no idea how to put it in my belt too because learning to use katana is a side thing.

so please, can u teach me how to somehow put the sheath in my waist? some holster or something? because if there were ever i need to use it, i cant hold both my katana and the sheath at the same time. nor would i risk putting my sheath down and pick it up later.

thanks in advance

PS: this was given to me, so i have no basic idea what kind of katana it is. All i can say is, its a simple katan you normally see in the movies. please forgive my lack of knowledge of this stuff too.
