Review on 📏 Accurate Precision: Grizzly T24514 5 Inch Woodworking Caliper by Jason Unruh

Rivets too tight, require a lot of force to open and close. I've tried silicone spray and wiggling my hands to try to loosen it, but to no avail. Will probably send them back. Otherwise, size, shape and material are fine. Update: They were replaced and the next set was even worse. Apparently, quality control is on vacation. If you just want to open and close them, you probably don't need the right caliper. If you don't mind fighting them and hoping they loosen up over time, that's up to you. You need to grind the sharp points so they don't scratch or pierce. Revain makes returns really easy.
