Abstract
A cove base cutting guide tool for guiding a knife through the guide tool and making a mitered cut on a cove base material. The guide tool includes a base and a plurality of tower members extending vertically from the base forming a first and second guide wall. The first and second guide walls define a groove having the same general shape as the cove base material to be cut. The groove includes a generally straight portion extending from a top to a bottom of the first and second guide walls with an open end at the top of the guide walls. The groove is wider at the bottom of the straight portion than the top of the straight portion. The first and second guide walls flex away from one another at the top of the groove when receiving the cove base material, and apply friction to the cove base material at the top of the cove base material when the cove base material is inserted into the groove. One or more slits are provided and extend through the guide walls along a predetermined angle and run transversely to the groove.
