Some use me and others dont but I’m good for pounding

You try your best, When the going gets tough, But what if your best, Just ain't good enough? Indecision creeps in, A niggling doubt, Constant struggle within, That you just can't shake out, Often it's paired, With a word meaning frozen, With what do you wrest, Before each option chosen?

When I cut things short, you might be relieved. Use me to butt in when you need to go. Often times between people I'm not well received. First part means between, the second: sounds like when a volcano's past ready to blow.

Fashioned from once-living skin, I exist only through you. I have a lying tongue and a blind eye. I remember paths in dirt, forget them in rain. Useless alone, directional in pairs. I protect, carry, and end every journey before rest.

Don't let the handle fool you Or the ugly faces too It's what's inside this that matters The ladies might have two.
