The MARSHALLTOWN 14 in. x 4 in. concrete finishing trowel with two rounded ends is constructed with the highest grade blue spring steel that has been hardened, tempered, and properly shaped. The rounded ends help create a smooth finish by preventing the blade from digging into the concrete. The aluminum alloy Xtralite® mounting is lightweight, but very strong. This concrete finishing trowel features a resilient DuraSoft Handle that is comfortable and reduces fatigue.
