The Diamond Products Ninja Joint Cleaning Blades deliver consistent performance for joint restoration work where standard blades fail. These specialized cutting blades handle the tough task of removing failed joint material while maintaining straight edges for proper sealant adhesion. The design addresses the specific challenges of joint maintenance, from removing hardened elastomeric sealants to cutting through contaminated expansion joints.
