Ten replacement SK2 high carbon steel blades for sharper, cleaner cuts. When you are wrapping cabinets, drawers, shelves or furniture with peel and stick vinyl, the blade matters as much as the finish. A dull blade pulls, drags and leaves rough edges, while a fresh carbon steel blade gives you control.SK2 is a high carbon tool steel used for precision cutting blades. The higher carbon content lets the steel harden well, so the edge grinds sharper and stays crisp through detailed trimming. That means cleaner corners, smoother edge cuts and less pressure on the surface underneath.Fit a fresh blade before the final trim, especially around handles, corners, joins and visible edges. If it starts to snag or drag, replace it. That small swap is what gives you a clean, finished edge.Fits the Velven Precision Trim Knife. Dispose of used blades safely and keep replacements away from children.
