EDIT:
Ice stone tools should freeze in place all non-Ice-type pokemon in the area when right clicked, making them easier to catch for some seconds.
I also feel that other tools and armor effects are too outdated and should be more related with the pokemon world, the leaf stone one acts like bone meal! It makes no sense to me to use its durability instead of real bone meal.
