Well, I know many of us predator folk have a retractable spear (me almost included ) and for those of us who don't, I'm sure there are a few questions. To start off, is it flimsy, or sturdy? Do you flick the extendable side out, or is there a release mechanism? Once the blade comes out, does is stay out, or fall back inside easily? Could you throw it like a normal spear? Are all them the same? (I mean the different websites with all the exact same pictures.) And most importantly, could you actually use it? Answer these questions, or just show your spears off!
