General Tools 6-Inch Flex Precision Stainless Steel Rule (300/1)

My main tool for string and pickup height

Buen material

Great tool to accurately measure small lengths

Precise and Handy Little Ruler This 6-inch stainless steel ruler has turned into one of those small tools I find myself reaching for constantly. The build is solid—made from stainless steel with clear etched markings that don’t wear off with use. Both inch and metric measurements are easy to read, and the fine graduations make it great for quick, accurate work, especially when I don’t want to drag out a larger tape measure. Its slim and lightweight design means I can slip it into a shirt pocket or a small toolbox without even noticing it’s there. I’ve used it for everything from marking wood cuts to double-checking small hardware dimensions, and it hasn’t disappointed. The flexibility is just right—not flimsy, but it gives enough bend to measure against curved surfaces if needed. If I had to nitpick, the 6-inch length limits it to small-scale work, but that’s exactly what it’s designed for. I wouldn’t expect it to replace a longer rule or tape measure, but for precision tasks and quick checks, it’s spot-on. Bottom line: A simple, reliable, and very useful pocket ruler that earns its keep in any toolbox, craft kit, or desk drawer.

Helps with guitar setups

I have used General Tools and Instruments for many years. Their steel rules are made in the USA and represent an excellent value. The six-inch pocket rule is excellent for technical work with both 1/32 and 1/64 inch graduations. The pocket clip doubles as a stop for depth measurements. Its small size makes it easy to carry in a pocket or store in a desk drawer or tool bag.
