The STARTUL Profi ST3525-035 precision try square represents the pinnacle of the series, offering the largest 350 mm blade for professional-grade layout on sizable workpieces. Its hybrid design—featuring a lightweight aluminum handle and a rigid, ultra-thin stainless steel blade—delivers unparalleled accuracy, durability, and ease of use for fine woodworking, cabinetmaking, and high-precision metalwork.

Key Features:

• Extra-Long Stainless Blade: The 350 mm stainless steel blade is precision-ground to a flawless 90° angle, providing an extensive, corrosion-resistant reference edge for verifying squareness and marking long lines on large panels and frames.

• Ultra-Thin Precision Profile: With a blade thickness of only 0.8 mm, it ensures minimal marking error and allows for exact scribing in tight joints, which is critical for high-end joinery and detailed mechanical layout.

• Permanent Etched Graduations: Features a wear-resistant, etched scale with clear cm/mm markings for direct and accurate measurements, guaranteeing long-term legibility even in demanding workshop environments.

• Optimal Balance & Control: The aluminum handle provides a perfect counterbalance to the long blade, reducing fatigue and improving handling for precise control during extended use on large projects.

• Comprehensive Angle Reference: Accurately checks and marks 90°, 45°, and 135° angles, making it an essential all-in-one tool for complex design, assembly, and quality control tasks.
