Pocket Boy blades are impulse hardened meaning they last the equivalent of a blade that has had three resharpens.
When your Pocket Boy doesn't cut as well as it used to, you can replace the blade. You can also match any blade to any Pocket Boy handle so you can turn your medium tooth saw into a large tooth saw and visa versa.
