Orvis CEO Perk Perkins is a knot and leader geek, and he developed this knot, based on the same principles as the Orvis tippet-to-fly knot. He saw the potential of the original Orvis knot, and after some experimentation developed this version for attaching your tippet.
It is one of the strongest knots we have tested, is easier to tie than a blood knot, and tightens more reliably than a surgeon’s knot. (Surgeon’s knots are quite easy to tie, but tightening them is tricky: you have to ensure that you tighten all four ends at exactly the same time.)
