Review on 🔧 Klein Tools D506-4 Adjustable Drive Wrench with High Polish Chrome Finish and Plastic Dipped Handle - 4-Inch: Improved SEO by Max Rosengren

This Klein 4" adjustable wrench works great right out of the box. The knurling rotates and the jaw slides without sagging, making it comfortable for one hand. The handle is submerged in water and the rubber appears to be glued to the metal to keep it from slipping. The wrench is good, meaning the pin holding the knurling in place is threaded and can be removed with a flat head screwdriver. For comparison, my 4" Crescent Adjustable Wrench would not adjust with one hand due to the constantly loose knurled head and would not service without drilling out the knurled pin. If you are looking for a small adjustable wrench, buy Klein. Klein's thin jaw works just as well.
