Hi @steveduf and others.  I have had little success in locating bull frog leather.  Then I remembered that the Australia Cane Toad is causing big problems in Florida, and was going to joke with you that we should go into the tanning business down there and clean up.  Well, I went on eBay and there were hundreds of auctions on them.  You know I am going to get me some of that.

But at $9 each, they may be worth a shot.  Kind of like a public service.  I think that the cane toad emits a toxic substance when frightened.  One hopes that they died peacefully to avoid a constricted bowing hand while practicing.

Hi @steveduf and others.  I obtained a tanned leather skin of a cane toad.  It looks like one could obtain between six to eight grips out of one, which is not that economical since I can easily obtain 500 grips from a $20 kangaroo hide compared with $14 for the cane toad.  

One aspect of the cane toad hide intrigues me.  There are two approximately 5/8 inch diameter crowned areas, which I suspect were located over the eye areas of the creature.  If a crown were placed on the position of wear on the grip, it would take a very long time indeed before such a grip required replacement.

So much for my anatomical geography.  From looking at the photos in this thread, the protuberances I described clearly fall over the fore limbs.  The received hide is quite flexible and is ready to use (I feared that it would be the stiffness of cardboard).

It is an ill wind that blows no good.
