This short video illustrates the major advantage of metal-bladed skates over bone skates. Even if the earliest metal-bladed skates were used with poles (I’m not sure when people started pushing with their feet), it was much easier to turn on them.
Here I’m trying to keep the hockey circle between my feet on my archetype skates (left) and on my bone skates (right). Note that it actually works with the archetype skates! The bone skates keep going their own way.
