I know this sounds a bit like an oxymoron, but do you have a favorite seam ripper? I had one for eons, and decided it really was too blunt to be any good any more, so replaced it with <I don't remember what brand or where from> seam ripper. The new one was so sharp, I loved it! Sadly, it vanished from my sewing table recently (I think it may have rolled off, unnoticed, into the trash), so I bought some replacements (generic brand, Amazon) and I am so disappointed that they seem about as blunt as the really old one I first threw out. Probably serves me right for going generic.

Does anyone have a recommendation for a good, reliable, and sharp seam ripper??

And on a fun related note, when I was growing up my mother called this item a "quick unpick", not a "seam ripper". Anyone else familiar with that term?
