I bought a cool looking torque wrench a while back at an estate sale but I didn't notice that the tip doesn't rest at zero, but about 2.5-3 inch pounds going clockwise. It's an older CDI torque wrench, by what I've read it's a really good brand. So, is this fixable or did I get a decoration piece? Sorry for no pictures but my phone is acting up right now. Thanks for the help.
