The square heel on this 12 Philadelphia pattern trowel holds the most mortar and has become the most popular pattern for use with block. The blade and shank are forged from a single piece of uniquely formulated carbon steel for extra toughness. Forging also assures product consistency. Blades are heat tempered with a special time-tested process to ensure uniform blade hardness. Each W. Rose masonry trowel features a tapered ground blade for flexibility. The forged steel blade and shank offer strength and integrity with no internal voids that could form if it was welded. Forged steel will not weaken or crack. Each blade is carefully hand polished to keep mortar centred on the blade and to resist sliding. The standard shank angle is specifically balanced to reduce wrist fatigue. Every trowel is inspected, keeping in mind the high quality standards of the W. Rose legacy. The 5-1/2 leather handle absorbs moisture while retaining a consistent grip. Proudly made in the USA.
