I tend to use one of my horn handled whips for mounted hunting, and the knob whip (actually, made for my older son by a friend, when he was a tyke and we lived in VA but hey, he hasn’t used it in years!) for walking out and foot hunting. But to be sure, have seen knob whips used by lots of veteran foxhunters in the field over the years.
If you want the most potential utility, the antler handle has many more uses in the hunt field. Either whip type can be used, say, to pony a horse or as a makeshift lead for a hound. But that antler is handy for getting gates and retrieving stuff that falls on the ground. Like caps/helmets, or gloves, yes I have fished one up that way. Would not work on a flask, though, so don’t anybody drop one.
I’ve never made my own, but have friends who do.
