I gave up on povidone and alcohol swabs in the kit cuz they were dried out due to the packaging fragility when I needed them. Wound irrigation with clean water is effective if large quantities are used: er docs typically want a liter or two on a small wound, orthopedists can fill a garbage pail in irrigating an open fracture. Instruments can be sterilized with direct heat or boiling water. Povidone wet-to-dry dressings are effective, but occasionally IME have caused local sensitivity reactions. Regarding cleavers: cleavers are designed to provide a little more mechanical advantage than a knife by offering a longer lever and a bit more mass. A splitting maul provides a much longer lever and much greater mass. Everything in between is a compromise. An earlier thread suggested that one can do just about all that is really needed with a pair of emt shears, which seems in my experience to be true: eliminate the knives, machetes, ahtchets and mauls, and maybe the povidone swabs won't be needed.

Tough to imagine Jim Bowie triumphing on the sand bar with a pair of scissors, tho...
