Abstract: A hammer handle is made of a spring strip formed into an oblong closed figure and a synthetic resin handle body molded around the frame. The closed figure is interrupted at one point along the front longitudinal side. Abutment of the free ends at the discontinuity prevents the frame and thus the handle from flexing in one direction when the hammer claw is used, but the free ends part to permit the handle to flex in the other direction and thereby reduce the shock resulting from striking a workpiece.

Abstract: A hammer of the type that includes a column of vertebra members is made of vertebra members having mating upper and lower abutment surfaces. Parts of adjacent abutment surfaces are mating concave and convex surfaces that slide across each other during pivoting in one direction so that the length of the shaft passage through the vertebra members is not increased during flexing of the hammer. Another portion of each abutment surface requires lengthening of the shaft passage if the vertebrae are to pivot in the other direction. Consequently, a shaft extending through the shaft passage and fixed at its upper and lower ends to the head and handle, respectively, prevents flexing in one direction but not in the other. Furthermore, the overwhelming majority of the resistance to flexing is provided by the shaft, not by interference between vertebra members, so the shaft size for a given resistance to flexing can be relatively large.

Abstract: A flying gaff, useful in gaffing large fish such as sharks, comprising a hook containing an elongated shaft and a wing member mounted on said shaft such that the wing member is capable of rotational movement around the shaft with little axial movement, said wing member having an aperture at its lower extremity through which a rope may be readily attached and detached. The gaff also includes a handle to detachably receive the lower extremity of the shaft such that the shaft may be readily urged into and detached from the handle.

Abstract: An improved fishing gaff having a hook with an elongated shaft, a handle comprising a tubular member and a cylindrical supporting member to receive the shaft and the handle. The supporting member has a length equal at least that of the shaft and has a channel disposed on its outer surface for receiving the shaft. The width and depth of the channel are equal to or less than the o.d. of the shaft and the supporting member contains means to restrict its length of insertion in the tubular member. When the shaft is inserted in the channel and the supporting member is inserted in the handle, axial and rotational movement of both the shaft and the supporting member are restricted.

Abstract: A tool assembly for mounting bits includes a tubular shank with an enlarged end portion in which is seated a tool bit receiving socket and its other end inserted into a handle. The socket has a cavity opening at the outer end in which is seated the body portion of tool bits. Releasable retaining means in the cavity retains the inserted tool bits which seat against a shoulder therewithin. The socket itself has a peripheral collar seated against the end of the shank and seats internally against a shoulder within the cavity of the shank provided by the enlarged end portion.
