I do alterations and repairs for a clientele. Since there is such a diversity in repairs I do, I keep an END NIPPER in my sewing tool drawer. This tool is like a plier in the way it functions in the hands but the tapered claw on it allows me to pry the stops off zipper tapes easily to replace the pull. I can use the same tool to replace the zipper stops on the tape. The end nipper also gets under grommets and makes it so easy to clip them away and off the fabric.
In addition, I keep several other small hand tools in my sewing tool drawer –especially the smaller size you now see in the jewelry craft aisle. They are handy, clean, rust free when I need them!
