Marshalltown Blue Steel Fully Rounded Concrete Finishing Trowel 20X4 (MXS20BRD) is a 20 x 4 inch fully rounded concrete finishing trowel with a blue-steel blade — the higher-carbon flexibility tier above the standard MXS line, broken-in faster and finishes flatter. The blade is forged from high-carbon steel and tempered for production-grade durability — the steel takes a working edge, holds shape under repeated impact with brick or block, and resists the corrosion that comes from constant contact with wet mortar.
This trowel handles professional concrete finishing where the blue-steel blade’s pre-broken-in flexibility produces a smoother burnish. Marshalltown trowels are the trade-default tool that every working masonry pro and concrete finisher learns on — the brand’s been in tradesman’s hands long enough that union apprentices get one in their first kit. Daily working use; oil the blade after a long pour or wet day to extend service life.
