Shinai maintenance

Nice video. It's always nice to see someone who shares the same passion as you do.

what is a shnaina

A bamboo practice "sword" for the Japanese Kendo art.

its useful for almost all combat arts/sports in which you fight with swords, cause bokkens could be hard sometimes ;)

the bamboo-sword he's assembling.

Buy a couple of shinai to use as spare parts. Actually they don't cost much so when its worn or breaks just throw it away and get a new one.

Right, you obviously do NOT train kendo. You probably watch some kendo vids on youtube and learn on your own.

You need to learn how to explain. Your sentences makes no sence.

My sentences make perfect sense. It's you who don't understand.

"what?" // mizutakendo.
I've linked this vid to several kendokas in my club, they too do NOT understand anything what you're writing. As far as I know everyone of us got straight A's in english.

I have a perfect explanation: krabykevin is either trolling or misinformed. There is no such thing as the god-shinai that he talks about.
There are however, varying levels of quality of bamboo, but all shinai are constructed according to the exact same method and have the same parts, which are demonstrated by Inoue-sensei in the video.
