Abstract
A manual tile cutter includes a base adapted to support a tile, a rail connected to the base above the tile and a carriage slidably mounted on the rail. A manually operated lever and a cutting toolholder are independently pivotally mounted to the carriage at a common pivot point. A shaft has one end mechanically coupled to the cutting toolholder and an opposite end extending through the carriage and connected to a manually adjustable knob. A biasing element applies a force on the cutting toolholder toward the tile. A height adjusting device in mechanical communication with the knob and the cutting toolholder adjusts the height of the cutting tool with respect to the tile but independent of the lever to accommodate different tile thicknesses.
