This Marshalltown Finishing Trowel is crafted from the highest quality hardened and tempered spring steel. The aluminium alloy mountings are fully heat treated for strength, polished and machine finished to ensure an ideal handle-to-post-fit, and are lightweight but extremely strong. The hardened steel rivets, holding the mounting to the blade, are properly sized and computed fitted for added strength. Since Marshalltown Trowels are not welded, there is no embrittlement problem to cause premature breaking. This tool is fitted with a resilient DuraSoft handle which offers a soft feel, reduces fatigue and offers excellent robustness.
