not the OP of this thread, but a woman with similar feelings: I know of and use the techniques you mentioned and I own a gripping tool, and I would still really like it if opening a jar did not take 1-3 minutes of effort and strain and specialized tools and occasional mild wrist pain, but rather was the 5 second easy painless action that it seems to be for most(?) men.
