Hi im richard and i just bought the BCBIN ultimate survival kit. It consists of a water bag, nylon cord, wiresaw, ziplock bag, waterproof immediate survival instructions, sewing kit, safety pins, fishing kit, flint and steel striker, emergency whistle, book matches, signalling mirror, button compass, single edge blade, multi purpose mini tool, x2 salt sachets, candle, pencil, x20 water purification tablets, brass snare wire. I used all the book matches so replaced them with water and windproof storm matches. sorry for the long post, but is their anything else absolutely essential i should add to this kit? I'm new to this kind of this thats why i'm asking, thanks
