The ruler functions as a precision measuring and scribing guide on all surfaces. The magnetic feature is especially useful when working near metal machinery, saw fences, or router tables, keeping the gauge anchored while you mark. On non-magnetic surfaces simply press-and-hold or clamp — the slip-resistant base keeps it in place.</p> <h4>Q: Can this woodworking guide gauge be used for both metric and imperial measurements simultaneously?</h4> <p>A: Absolutely. The dual-scale design displays millimetre and inch graduations on the same ruler, so you can switch between measurement systems i
