The Carpenter’s Standard: The 6-Piece Heavy-Duty STRYI Profi Straight Chisel Set

In architectural carpentry and furniture restoration, the flat chisel is the most used—and most abused—tool in the chest. To handle the mechanical stress of deep mortising and heavy waste removal, a tool needs more than just sharpness; it needs mass. This 6-piece STRYI Profi SET is engineered with a substantial 5mm metal thickness, providing the rigidity and vibration damping required for clean cuts in seasoned hardwoods. Whether you are fitting a hinge, cutting a tenon, or leveling a broad flat surface, these tools offer the structural stability that thinner consumer chisels lack.

Workshop Logic

This set is curated as a "Full-Scale Joinery System." In a professional workshop workflow, you need a range of widths that correspond to standard hardware and timber dimensions. The 8mm and 12mm chisels are your specialists for fine mortising and detail cleanup in tight joints. The 20mm through 24mm tools are the workshop workhorses, optimized for furniture framing and hardware installation. The massive 30mm chisel acts as your primary leveling engine, clearing waste across wide planes with a single, controlled pass. Designed for high-impact use, this set bridges the gap between delicate carving and heavy-duty carpentry.

The “Pro-Steel” Advantage

• 65G Spring Steel: Forged for extreme toughness and impact resistance. This steel grade is specifically chosen for its ability to absorb the energy of mallet strikes without chipping or deforming.

• 60–62 HRC Hardness: Hardened to an elite level usually reserved for carving tools, ensuring professional-grade edge retention even when working through abrasive end-grain.

• 5mm Metal Thickness: This "Professional Rigidity" profile eliminates blade flex and chatter. The added mass provides a more stable cutting experience, ensuring the edge stays true to your layout lines during deep paring cuts.

• European Oak Handles: Finished with natural linseed oil, these handles are designed for durability and a secure, comfortable grip during prolonged sessions of heavy material removal.

• Mallet Compatible Construction: Engineered to withstand the repeated force of a wooden mallet, making this set suitable for structural joinery and deep excavation.

• Manufacturer-Direct Quality: Produced in our Ukrainian forge, ensuring direct accountability for the metallurgy and geometry of every blade.

What’s in the Kit

• Carpentry Chisel 8mm: The precision joiner. Ideal for cleaning out small mortises, dovetail intersections, and narrow grooves where millimetric accuracy is required.

• Carpentry Chisel 12mm: The mid-sized specialist. Optimized for standard cabinetry joinery and fitting smaller hardware components.

• Carpentry Chisel 20mm & 22mm: The framing essentials. These widths are perfectly calibrated for cleaning out housing joints and preparing timber surfaces for structural assembly.

• Carpentry Chisel 24mm: The hardware architect. Designed to match the dimensions of common industrial hinges and locks, facilitating faster and cleaner installations.

• Carpentry Chisel 30mm: The leveling engine. Its wide edge is essential for clearing large amounts of waste, paring broad tenon faces, and achieving a tool-finished flat surface across wide boards.

Complete Your Workshop

• STRYI Professional Leather Sharpening Wheel: The industrial-grade solution for maintaining wide-profile chisels. Hand-sharpening a 52mm blade on stones is a drain on billable workshop hours. 

• STRYI 4-Piece Versatile Wood Carving Kit: The strategic bridge between structural carpentry and aesthetic refinement. While your heavy-duty chisels handle the primary joinery, this versatile set—including whittling knives and detail gouges—allows you to execute the high-value relief carving.

• STRYI 30x20cm Premium Basswood Practice Board: A zero-defect medium for technical testing and complex layout. This 2cm thick, knot-free Linden board provides a "buttery" consistency that allows your chisels to glide without the risk of grain-related tool deflection.
