I've done several antler-tipped rods and they definitely look different & nice. I have never used one on a gun when going into the bush but have occasionally taken them to the range.
I carved the basic shape with hand files and a knife. Next I reduced the tip of the rod and drilled a hole in the antler to fit. The rest of the shaping was basically done on a two wheel grinder and finished smooth with sandpaper. I glued them on and normally would
carefully pin them.
I made this one for my smoothbore.
Here's one on the third rifle from the left.
