Alpine Butterfly bend
An Alpine Butterfly bend) is a bend based on the alpine butterfly loop. it is not widely used probably because it is a little confusing to tie and does not offer significant advantages over other bends.
If you still don't get it' it's the knot you'll get if you tie an alpine butterfly loop and cut the loop, so you have two rope ends.
