Right now I’m in the middle of a little experiment. I’m making two bullwhips, these are cowhide leather bullwhips made with 8 plait overlays. Where they are different is the internal construction. One bullwhip has a flared core and a plaited belly. The other has a straight core, plaited belly and a bolster.
When I use the flared core the idea is reduce the drop off at the end of the handle foundation when using a spike for the handle. That’s the same thing that’s accomplished by using a bolster that starts at the end handle (ie not covering the whole handle). However by using a bolster you get the advantage of it filling up air pockets in between plaited layers.
Normally when I make kangaroo bullwhips I do both a flared core and a bolster that doesn’t cover the entire handle. However these whips that I’m experimenting with are cowhide whips and are intended to be made to sell for less. So the less time I can devote to them the cheaper I can sell them.
I’m hoping that I like how the one with just the flared core performs because it’s less work on my end.
