Abstract: A portable pair of skis may be packed in a small case for convenient storage and carrying. In one embodiment each ski is readily disassembled into two pieces, each ski piece having an end plate which mates with the end plate of the other ski piece. An assembled ski, which will function as originally designed and intended, comprises a bottom joining plate, which spans the two pieces, having four posts which are fixed to the bottom joining plate and which protrude through holes in the ski pieces and a top plate securing nuts, nut bearing plates and a removable over-center cam-action fastener which joins and applies tension to the two adjacent posts at the end plates. In another embodiment, the bottom plate is hinged and permanently fastened to the two ski pieces and two posts, which are fixed to the hinge, protrude through holes in the ski and the top plate. A removable over-center cam-action fastener is removably connected to the two posts via the grooved securing nuts.
