Sign up for Heavy-Duty 20.8-Inch Metal Ruler – Stainless Steel Dual Scale (cm/inch) With Self-Defense Potential (5mm Thick)
This isn't your kid's school ruler.
This is a 20.8-inch slab of stainless steel that measures thick and tough—literally.
At 5mm thick and weighing in at around 550g, it's built like a tank.
It's a precision ruler with clear dual markings (centimeters and inches) on both edges, so you can measure accurately in workshops, construction sites, or just around the house.
But here's the twist: it's solid enough to double as a self-defense tool if you ever need it.
Not saying you should go looking for trouble, but having something this sturdy in your car or toolbox isn't the worst idea.
It's practical, functional, and gives you a little extra peace of mind.
Great for DIYers, craftsmen, or anyone who needs a reliable straight edge that won't bend.
It also works as a level or a small pry bar in a pinch.
Multi-purpose, durable, and built to last.
