Marshalltown Finishing trowels, whether for concrete or plaster, are made of the highest quality polished hardened and tempered stainless steel. The aluminum alloy brackets are fully heat treated for strength, they are polished and machine finished to ensure an ideal handle for post-adjustment, and are lightweight yet extremely strong. Hardened steel rivets, holding the mounting on the blade, are properly sized and adjusted for strength. Since Marshalltown trowels are not welded, there is no problem of embrittlement to cause premature breakage. This tool is equipped with a durable DuraSoft handle that provides a soft touch, reduces fatigue and provides excellent robustness.
