Cover art for My Valuable Hunting Knife lyrics by Guided by Voices

Maybe this is me just being overanalytical and/or crazy, but I think "my valuable hunting knife" is a sex toy of some sort. Or some non-human thing that gives pleasure to whoever's point-of-view this is from. Between the lines "She will shine like a new girl" and "And it will not lose its appeal over years", It's one of the few things that makes sense off the top of my head.

I always thought it was a stalker/murder song. Using the knife literally or possibly metaphorically to cut away or kill the old life.
