Review on 🔧 Silicone Rubber Tool - EZ Grip 77mm Lens Repair & Filter Wrench: Scratch-Free Front Retaining Ring Removal made Easy by Robert Elder

I used this to disassemble a Pentax 300mm f4 Takumar lens and it worked great! It is a wrench consisting of a ring-shaped, black anodized aluminum handle with a rubber friction ring inserted inside. It is designed for unscrewing threaded parts with a diameter of 77 mm. It's an excellent tool and does exactly what it's supposed to do and it couldn't be better. I highly recommend this tool and its other sizes to anyone who wants to work with camera lenses.
