    Abstract: A wire strainer has a ratcheted spool rotatably attached to a frame to rotate in a desired direction when tensioning and able to freewheel otherwise. At least one oval/elliptical hole in the shaft accommodates one, two or more wires therein in a particular orientation on the shaft. The oval/elliptical hole is adapted to be dimensioned and positioned on the shaft such that the integrity and strength of the shaft is not compromised or lessened. A projection and a two plane guide means can be situated on the spool whereby the projection is positioned and engages with a portion of a wire and the two plane guide is positioned and assists in deflecting the length of wire not engaged with the projection away from the projection as the spool is rotated during the straining of a wire. Y-shaped reinforcing ribs on the frame provide strengthening and rigidity while tensioning.
