Our Tinker Bastard swords by Paul Chen of Hanwei are based on the Oakeshott Type XVIIIA and is designed so that both the sharp and blunt versions of the sword will perform identically in the hand, offering the possibility of sparring and cutting with swords that feel and respond in exactly the same way. The sharp blade is produced in two slightly different versions - this version is diamond-sectioned throughout its length. Wheel-type pommels are sized to provide a grip for the second hand when required, and the straight tapering cross section provides excellent hand protection. See Hanwei's model .
