If you ever need to measure something quickly but don’t have a ruler or tape measure nearby, your index finger can be a surprisingly accurate tool. For many adults, the distance from the tip of the index finger to the first joint is approximately 1 inch. Even more interestingly, the entire index finger often measures around 3 inches in total.

Its flat, circular design allows it to glide smoothly across the ice at incredible speeds ideal for slap shots, passes, and precision plays. Built from vulcanized rubber, it’s engineered to withstand powerful hits, harsh conditions, and non-stop action.
