This is our first (and only one that we're aware of) bokken made from g10, a fiber glass phenolic. This material is semi-translucent when it's thin, and is incredibly durable. This bokken is the first of it's kind.
This g10 bokken weighs 1105 grams (2lbs 7oz) and is blade heavy, which makes it very close to feeling like a shinken. It's a bit heavier than a standard bokken due to the density of the material, but it's perfect for practicing with the feel of an actual shinken, without the dangers involved with a metal sword.
