This wonderful tool (I used to keep several around everywhere, including my knitting bag, is a tool with a tiny crochet hook on one end and (here's the special part) a thin, slightly bent tip on the other. The joy of this tool was that this tip enabled you to get knots, almost any knot, out. As a weaver, knitter, this tool was invaluable. It used to be for sale at Patternworks in Poughkeepsie NY. Any clues anyone? Thanks. spiritweaver
It sounds to me ..... it could be a tool for knittingmschines.
My brother KH940 has had a tool like this what you described.
Ask anyone for it, who is a owner of a knittingmaschine.
Contact any dentist office and I'll bet they can at least tell you what they're called. From there you can google it. However, if its what I think it is, check in the pharmacy tooth section of Walgreens or Walmart.
