A professional 9 piece stair tool kit with interchangable blades made from high grade chrome-molybdenum. Each of the blades can be quickly detached by pushing down the locking pin located on the handle. The design of the blades allows you to set the carpet into tack strips as well as drive carpet into gullies and crease the carpet along the wall line with ease. The flat edge of the blades also prevent the tools from damaging the carpet.
