I like the small Fiskars scissors with sharp tips; have several of them on hand. Don't like their large scissors as much because, in my experience, they don't stay as sharp as I like. The Martelli rotary cutter is much easier on the wrist; well worth investing in one of those, although it does take some getting used to. (Not sure if it works well in the June Taylor strip cutting mat, though; can't remember.) The new electric Accuquilt Go Big! is probably easier on the wrists too, because you don't have to hand crank.
I was diagnosed with severe carpal tunnel in one hand and moderate in the other. I was able to reverse mine by catching it early enough to radically change my routine. Completely changed my computer setup to become better ergonomically, cut my typing time at the computer in half, invested in hand splints from Walmart (the kind with metal inserts up the palm) and wore those day and night. The splints keep your wrists in a neutral position, reducing stress on the carpal tunnel.
Also took citrus bioflavanoid supplements -- two in the morning and two at night; here is a link to my favorite brand:

I had read online somewhere that citrus bioflavanoids help reduce the inflammation of carpal tunnel.
I met a dental hygienist who developed severe carpal tunnel syndrome after spending days removing wallpaper in an old house. Hers was so bad she had to quit her job. She also took citrus bioflavanoids and, like me, thought they helped. It took her several years, but she finally improved enough to be able to go back to work without pain.
