Reusable karate striking board

A striking board kit comprising first and second substantially rigid parts, said first part and said second part having matched edges and matched concavities in said matched edges, and a plurality of severable insert parts, each insert part having a portion thereof removably insertable in said concavities of said first and second parts to render said matched edges contiguous and temporarily joined along an elongated junction, the strength of each insert part being sufficiently great to require a strike of a predetermined force at said junction to rupture said insert part the construction of each insert part and the removable connection between said insert part and concavities being such that said strike of a predetermined force will necessarily rupture said insert part, said ruptured insert part being removed from said concavities for insertion of another of said plurality of insert parts into said concavities thereby rematching said edges of said first and second parts to once again permit rupture by a predetermined force.
