If you're determined to test whether your index finger is stronger than someone else's, or stronger than your ring finger, or your little finger, or even your middle toe, then this is just what the psychiatrist ordered.

All you do is simply attach the hammer head to your finger and whack this old-world-style strength machine as hard as you can to see if you can ring the bell, just like the full-size machines at the fairground. And when your fingers are all worn out and shaking from the effort of proving how tough you are, don't forget that the kids might also enjoy having a go, and grandparents too, and they might just surprise you with those gnarled and pudgy fingers. It's a charming little miniature nostalgia trip for all ages.
