An elongate metal structural member is cut off transversely of the member by engaging one side of the member with a beveled cutting edge of a blade, supporting the member on a side opposite the blade, at support positions spaced from respective opposite sides of the median plane of the blade and forcing the blade through the member. The cutting edge is symmetrical in cross section about a median plane of the blade. The structural member may be an ungrouted, hollow, tubular member, for example a support pile for a deep sea drilling or production platform. The cutting edge may be supplemented by two secondary beveled cutting edges transverse to the primary cutting edge for engaging sides of the tubular member to cut lateral bulges that may be formed by flattening of the member as it is pressed between the primary cutting edge and the support.
