  • Patent number: 5065516
    Abstract: disassemblable scissors which utilizes a releasable pivot joint between pivotable scissor halves. The pivot joint is formed in the scissor halves between the blades and the handles of the scissor. The scissors halves are pivotally retained together over a range of cutting motions by a retaining assembly. The retaining assembly retains a portion of one of the scissors halves movably within a retaining portion of the other of said scissors halves at least over the range of cutting motions. To release and disassemble the scissors, the scissors halves must be pivoted at least past the range of cutting motions to a point where the portion of the one scissor half is no longer retained by the retaining portion of the other scissors half. In this position, the two halves can be transversely pulled apart.
