Marlin Splice + bury = Locked Brummel
BTW, the two passes through the standing part, prior to the bury, are called a Marlin splice.
Marlin is two strand, twisted, tarred hemp... it is small stuff, used for a variety of things, including mousing shackles, seizing shrouds, knife lanyards and breakout ties for sails.
Being two strand, it cannot not be spliced in the traditional manner, so it is spliced with three passes through the standing part, like the two passes Opie has shown prior to the bury. It is surprisingly strong, and doesn't reduce the strength of the line much at all.
