A saw tooth setter has a carriage within a housing. A carriage base has a channel which narrows from a first end to a second end. A wedge protrudes up from the base in the channel. Mechanical linkage translates movement of an actuator into forward and backward movement of the carriage. A second mechanical linkage translates movement of the carriage to forward and backward movement of a blade feeding arrangement. A setting mechanism has a set of opposing plates which extend through and are hingedly attached to the top cover. The first end of each plate is seated in the channel. The second end of each plate has sets the tooth. Upon forward movement of the carriage the first end of the plates enter the first end of the channel and are separated by the wedge, and the second end of the plates come together to set the teeth.
