I found the rotary cutter on a slide helps because you don't have to grip it you line it up and press down and push.
do you drink lemonade, funny question i know but it can agravate arthritis cutting it out can help.
I was talikng to a gentleman who told me his arthritis was so bad he ended up seeing a specialist who told him not to drink lemonade. and it settles down, lemon drinks are fine it is just the lemonade
