Marshalltown's new DURAdjust brick trowel has a dial that lets the user adjust the handle's diameter throughout its length, from just below the smallest on the market to just about the largest, for personalized comfort. Changing the diameter throughout a day of use helps decrease arm and hand fatigue, the maker stays. It is available on 19 different trowels, and is made with the same high-quality bumper material as the standard DuraSoft handle. Price: $45. 800-888-0127.
