It doesn't make a lot of sense to say that an axe can cut a long slit in a purple worm's stomach (so the PC can get out) but a dagger can't. Axes are for hacking deep, but short holes. A dagger (or shortsword) would be the thing to use for drawing a long, slice to escape from.
And the spiked gauntlet, light lance, or light pick?
