The KDS Stainless Steel blades are less hard than standard steel blades.
Hence, they are less likely to scratch glass.
The SB-50S EVO-S has a buffed finish edge. They cut films easily but are less subject to scratching the surface of window/automotive glass.
This makes it a very popular choice when working on glass, whether it is for cutting tinting film or vinyl.
