Designed for removing O-Rings, this tool can be used for a variety of purposes and is a nice, affordable addition to your tool box. Not being a precision tool, you can pick up just about any set available in what ever price range you are willing to pay. I recommend your kit include: 1-pc. Full Hook, 1-pc. 45-degree, 1-pc. 90-degree, and 1-pc. Straight Pick.
