Coldsteel Unbreakable Bokken Description

Training with a “live blade” is great if your practicing tameshigiri or cutting. However, when it comes to partner practice it can be a little dangerous and you are likely to quickly run out of training partners. So the Japanese used Bokken, simple wooden swords as training weapons to improve their skills with a lot less injuries. Over the years, Red Oak Bokken and White Oak Bokken have become the standard for wooden bokken but there are many varieties. The hardest varieties are made from extremely tough wood including the Japanese Green Oak. This nowadays is very expensive and Coldsteel have developed a synthetic substitute. 


These coldsteel unbreakable bokken are virtually indestructible and used for what they were intended are unbreakable. They don’t split or splinter like wood can and are completely waterproof and rot proof. Not only that, but Coldsteel unbreakable bokken have been designed to be the same weight, length and size as a standard katana so transitions to training with a ‘live’ katana is as smooth as possible.  


Perfect for partner practice and sparring training, however if you use one against a wooden bokken you may break a lot, so it's best if you train against another Coldsteel Unbreakable Bokken. They also fit the plastic saya we sell at Enso martial arts so you can practice drawing the sword too.


Advice from the shop on Coldsteel Unbreakable Bokken

“They do feel a little odd, they are designed to be the same weight as a katana rather than a bokken, so can feel a little light. Don’t let that fool you, these bokken are an amazing weapon from Coldsteel and a great modern addition to the training kit for a Japanese martial arts practitioner.”

The grip gave me blisters. It's rough like sand paper.
I purchased tennis racket tape to fix it but it's a big flaw.

Great for practiting but, tsuka is slippery because its plastic, easy to solve it just wrap it with boxing bandage or wear gloves.
