with bat ray pretty much what it is. barbs around 3 to 5 inches on a ray that size, when you land them and you not paying attention, and i was not, they curle there tale up and try to stick it to you. ussuly first order of business is to step on the tale and run you knife under the barb and cut it off. I went to pull the gaff and hook out first. i reached back to hold him down and he slipped it into my palm, nice little 2 inch scar. yanking my hand back opened it up, its barbed full length kinda like a saw, was not deep, like a large splinter, removed the gaff, hook and through him back, lesson learned.
