Mayhew 3″ x 7-1/4″ Brick Set

The Mayhew 35102 brick set combines traditional masonry design with heat-treated, high-carbon steel construction. At 3-1/2 inches wide and 7-1/4 inches overall length, it’s sized for standard brick cutting while remaining compact enough for precision work. The forged steel construction and shot-blasted finish deliver the durability Montana masons need for foundation repairs, chimney rebuilding, and hardscaping projects.

Worth it for contractors who cut masonry regularly. The heat-treated blade meets ANSI specifications and comes with Mayhew’s lifetime warranty. At 1.32 to 1.7 pounds, it’s light enough for overhead work yet heavy enough to transfer hammer strikes effectively. Skip it if you’re just breaking up a sidewalk once. A cold chisel costs half as much and works fine for demolition.

Technical Specifications and Design

The single bevel design sets this apart from double-bevel alternatives — you get straighter, more predictable breaks when scoring brick or concrete block. The larger target-head striking area reduces mushrooming, which matters when you’re swinging a 3-pound drilling hammer all day.

Specification	Value
Blade Width	3-1/2 inches (8.89 cm)
Overall Length	7-1/4 inches (18.42 cm)
Weight	1.32 - 1.7 lbs
Material	Forged high-carbon steel
Heat Treatment	Heat-treated blade
Finish	Shot-blasted

The shot-blasted finish isn’t just cosmetic — it provides texture for better grip and rust resistance. That matters in Montana where tools sit in trucks through temperature swings from -30°F to 90°F.

Real-World Applications

This tool handles four primary masonry tasks: cutting and shaping brick/stone/concrete, scoring masonry for precise breaks, trimming excess mortar from brickwork, and general construction work including foundation repairs and bricklaying.

The proper technique involves placing the chisel against the masonry surface and striking with a drilling hammer. For clean breaks, score the surface first before applying a final, heavier strike. Works with standard striking tools — drilling hammers, small sledges, and ball-peen hammers.

The compact size shines in tight spaces. Think crawl space foundation repairs where you can’t swing a full-size sledge, or chimney rebuilds where you’re working from scaffolding. The 7-1/4 inch length gives enough leverage without getting unwieldy.

Build Quality and Durability

Mayhew backs this with their lifetime warranty, standard across their USA-made tools. The heat-treated blade exceeds ANSI specifications — not marketing fluff, but measurable hardness standards.

The larger striking head design directly addresses the biggest failure point on cheap chisels — mushrooming. Hit a standard chisel off-center enough times and the head deforms into a dangerous projectile waiting to happen. The expanded target area gives more room for error when you’re fatigued at hour eight.

Unlike wood chisels, this masonry tool is engineered for hammer strikes and uses harder steel formulated for abrasive materials. Don’t try using your finish carpentry chisels on concrete unless you enjoy buying new tools.

Frequently Asked Questions

What size hammer works best with this brick set? Compatible with drilling hammers, small sledges, and ball-peen hammers. A 3-pound drilling hammer provides the best control-to-power ratio for most masonry cutting tasks.

Can this cut granite or other hard stone? Designed for brick, stone, and concrete cutting and shaping. Works on most masonry materials but extremely hard stones like granite will dull the edge faster than softer materials like brick or limestone.

How does the 35102 compare to Mayhew’s other brick sets? The 35102 features a larger 3-1/2” blade and 7-1/4” length compared to the 35002 model (3” x 7”), providing more surface area for cutting larger bricks.

What maintenance does this tool require? The shot-blasted finish provides rust resistance. Keep it dry between uses, occasionally oil the striking surface to prevent rust, and regrind the edge when it dulls. The heat-treated steel takes a standard bench grinder well.

Is this suitable for demo work? Applications include general construction and masonry tasks. While it handles demolition, a dedicated cold chisel or demo chisel costs less and takes more abuse. This excels at precision cutting where you need clean, controlled breaks.
