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.
