The Trow & Holden CHT12SG (CS3) is a premium, heavy-duty stonemasonry hand tool precision-forged in Barre, Vermont, USA. Specifically designed for striking with a heavy steel mash hammer, this hand tracer is engineered to score clean linear guidelines and execute precise structural splits across the hardest varieties of natural stone.
Technical Specifications
• Part Number / SKU: CHT12SG (CS3 Classification)
• Manufacturer: Trow & Holden (USA)
• Blade Width: 2 Inch / 52 mm
• Shaft / Stock Diameter: 1 Inch / 25 mm
• Handle Configuration: Swept Grip profile (ergonomic hourglass contour)
• Cutting Edge: Premium Tungsten Carbide Tipped blade matrix
• Primary Application: Heavy-duty linear splitting, scoring, and edge trimming
• Target Substrates: Highly abrasive and dense stone types (including hard granites, quartzites, and structural sandstone)
Key Features & Core Benefits
• Exclusive Hourglass Swept Grip: The proprietary contoured barrel tapers dynamically in the middle. This architectural relief reduces overall tool weight while creating a more secure, slip-resistant hold. Users report a noticeably "softer" tactile impact rebound, which mitigates repetitive hand fatigue over long masonry shifts.
• Industrial Tungsten Carbide Tip: The ultra-hard carbide insert provides maximum wear resistance. Unlike standard hardened carbon steel tracers that blunt rapidly against crystalline quartz elements, this blade retains its splitting geometry through thousands of heavy strikes.
• True 1-Inch Shock Absorption Stock: Built out of a solid 25mm steel stock, the upper striking face is meticulously tempered to handle direct, high-impact blows from steel stone-hammers without mushrooming or fracturing prematurely.
• High Performance Splitting Geometry: The 52mm blade width serves as the industry-standard balance for managing straight fracture lines across varying slab thicknesses, concentrating kinetic energy straight through the core of the stone.
