Poor man's glaive/naginata. 
It would be easy as pie to make. Obviously nowhere near as durable as a real deep tanged weapon but it should handle water bottles no problem. $100 for the knife and $50 for a quality staff so I'd wager it would be safer than an equivalently priced polearm lol!
I'll see if I can get my hands on a #13 this summer. As of now I'm waiting on #9,#10,#12 in the mail to modify. You really cannot beat that price to quality ratio so its a great way to make a personalized gift. I'm going to try my hand at pyrography on the handles and I'm looking into acid etching the blades. I got inox. Feel free to post your opinel mods too!
