This tool is for removing tough mats and tangles without losing coat length. The TL420 Mat Buster features 10 blades to help you navigate through mats and tangles. The blade cartridge is reversible so it can be used by both rightys and leftys. The ergonomic handle is comfortable and features spots for you to put your index finger on the front and thumb on the back for total control of the tool. On both sides you will see flexible black rubber which adds extra comfort and allows you to keep a firm grip on the tool. The overall length of the Mat Buster is 7 inch from the top of the tool to the bottom of the handle.
