i had one that was pretty much exactly the same except it had the lighthouse form Peggy's Cove on it (I think) and my name on the back.
I think the first time I tried to use it I tried the screwdriver and the torque was enough for the brass pin to snap and the whole end f it came apart.
My suggestion would be to keep it for it's appearance and the memories it brings up and never, ever, EVER actually try to use it for anything!
