Tormek SE-77 Square Edge Jig – Precise Sharpening for Chisels & Plane Irons

Enhance edge accuracy with the SE-77 Square Edge Jig

The SE-77 is designed to help woodworkers achieve crisp square corners on chisels and plane irons with confidence. Built as an evolution of the SE-76, this jig emphasizes reliable contact, stable alignment, and consistent results on Tormek sharpening systems.

Key to its success is the adjustable side, controlled by two small knobs that you can loosen and tighten in seconds. This fast fine-tuning makes it easier to compensate for tools that are not perfectly square to the stone, very narrow blades, or steel that has a gentle twist. You can also set the jig for a slightly convex edge when your work benefits from a tiny curvature.

The SE-77 secures blades against the grindstone with safety stops, so you maintain control and protect your fingers while sharpening. Its robust construction is designed to hold wood chisels and plane irons up to 77 mm (3 in) wide, enabling a broad range of common workshop blades.

What you gain in practice

• Accurate 90-degree edges for consistent shaving and smoothing tasks
• Flexible troubleshooting for misaligned tools or twisted steel
• Support for tapered or Japanese chisels thanks to secure positioning
• Peace of mind with safety stops that keep blades on the jig and on the stone

Design and compatibility

• Compatible with Tormek t-3, t-7, and t-8 sharpening systems
• Newly designed to hold chisels and plane irons securely on the stone
• Option to set a slightly convex edge for specialized sharpening needs

Whether you’re refining your everyday chisels or tackling a more delicate, tapered blade, the SE-77 offers a precise, repeatable approach to sharpening. While it guides you toward precise geometry, the final result still depends on your technique, tool steel, and workpiece specifics. Use it as a reliable helper that broadens your options and supports accuracy in routine maintenance or restoration tasks.
