How Bogu Offer Protection (2)

The general bogu trend nowadays is to make it soft to ease movement.

However, today I think we would like to discuss the idea of structural hardness or shape elasticity.

Just as the article before, hardness or elasticity is the ability for a material

to return back to its original shape under stress.

In Kendo the first line of defense is the structural hardness.

At the moment of impact, the shape of the equipment will first distort it shapes,

that distortion allows it disperse the incoming force.

That is why among bogu craftsman, for example during

the making of the men they call it "Kumo Wo Tsukuru",

would make sure the hitting part is made in such a way

that it is hard and there is an air pocket between the men and user.

However, one must always remember there is trade off in design.

Usually between comfort or ROM and structural hardness.

So it is good to remember and know the purpose you have in mind and find the right bogu.
