You should probably go do a battery health check. If your range is that bad, your battery degradation should be within warranty replacement range.

I wonder where things like prybars fit into that. At work, knives are discouraged, so I carry a LNW prybar. If I'm being honest it's probably more functional than a knife for the things I do day to day like cutting tape to open a box, or popping tabs or as a flathead to open something. You know, things you really shouldn't be doing with a knife anyways.
