Query: Poor quality

Appears to be Chinese construction. Slider mechanism catches at certin points, without apparent cause. Added oil and gentle touch, little or no good effect noticed. Wiggling the jaws helps the slider move, but not convenient or a one hand tool like the old Crescent wrenches. I'll keep my Crescent wrench with the knurled thumb screw from the past and return this one.
