The ōtsuchi – a massive wooden war hammer from Japan – was never meant for duels… but sometimes, you don’t get to choose your weapon.
In this video:
- We build several versions of the ōtsuchi (including sparring-safe and heavy-duty)
- Sparring and crash test footage
- A short cinematic scene imagining how this weapon *could* be used in combat
- Real reactions, real weight, and a lot of smashing!
This isn’t your average samurai katana video. This is a tribute to an underrated piece of Japanese warfare – the breaching hammer.
📏 Weight comparisons:
Sparring version: 4kg
Medium wooden: 3.5kg
Heavy wooden: 7.5kg
Massive version: 13kg
🎥 All props built and tested by hand.
🛠️ No sponsors, just passion and bruises.
