I recommend to add tweezers, a lens, a mirror and some stainless steel wire (sometimes it´s handy even if you don´t need it for snares). I prefer disposable scapell blades to the razor. I also always carry a lighter and a spare battery for my flashlight.<br>I doubt that the iodine swab helps to treat water, but in your case that shouldn´t matter. IMHO the amount of antiseptics could be reduced (in first aid courses we discourage their use).
