Bisento Beech wood | Handmade wooden Bisen To

I've been looking for a polearm trainer of this style for a long time, and finally found one here.
The bisento itself feels great. It's a massive chopping weapon, and you really feel the weight that is in the front, all while barely limiting your movement. Finding kata and similar for the bisento isn't easy, but what I've used it for so far, it handles well, and quite comfortable.
There wood seems to roughen up a bit when used for some time, or coming in contact with water, but just drawing a sponge's rough side over it brings it back, so this is hardly an issue.

Advantages: Heavy, but still well-balanced
Great feel with the grip
Mobile even at the massive size
2.5 meters of pure awesome

Disadvantages: Wood changes texture when coming in contact with water/sweat - just draw the rough side of a sponge over it carefully to fix it
A bit difficult to actually store because of how big it is.
