Define your "bush"... because in the tropics and equatorial rainforests your point is 100% valid. But the undergrowth in a deciduous or pine forest does not need to be hacked and slashed away at in order to traverse. True an axe is not made for cutting small-diameter green stems, although a properly sharpened axe can and will do the job easily... just with that much more energy involved in swinging it. You also don't need leather gloves or "gauntlets" unless your hands are so virgin you'll get blisters within a half hour of use.
