If you're looking for a cheap, easy and (hopefully) accessible exercise to improve your grip strength and finger strength, try a cheap #TennisBall with a slit cut into one side. We call them "smileys" at work.
Depending on where you squeeze the ball, you can taylor the resistance to your liking.
I've been carrying one around in my hoodie pocket when I walk to work, or when I'm seated and reading.
HUGE improvements in just a couple days.
Total cost: $0.33.
