|One of the threads was talking about seam rippers. One point was we sometimes don't want to put out the money for a good one (one that cuts not pulls). I was just using my new one( a cheapie) and it was cutting fine. Then it dawned on me. How often do you replace them? We all know to replace needles, get our scisors sharpened or replaced, put new blades in the rotary cutter, and for special projects we buy new pins. We expect those hard used seam rippers to last for years or until we lose them. They have blades too and many of us are sewing with polyester thread which is tough. Seam ripping is never going to be a fun thing but we can give ourselves a break by making sure are rippers get replaced occasionally.
