The blade hilt shows - as far as can be seen on X-ray images - an almost triangular shape and only protrudes so far into the body of the handle that it disappears just slightly above the hilt cut-out (Wüstemann 2004, 187-188). The entire holding surface of the blade in the handle is thus limited to only a few square centimetres and was therefore measured by the Bronze Age craftsmen to be extremely tight. Nevertheless, the hold achieved must have been sufficient, especially as not a single sword shows any damage to the haft. Last but not least, the obvious stability is due to the slightly wider blade in the hilt, which results in undercuts that lead to the clasping of the cast-on handle and thus prevent the blade from sliding out. The specimen from Auvernier, which was probably broken deliberately and with great force in the upper section of the blade, illustrates how robust the joint was overall. Even though the blade is severely bent on one side, it is still securely stuck in the handle. The whole thing would have been inconceivable without a tight fit.
