Whatever you call it, the Castwell Knot is a simple, effective, durable, good enough ( s.e.d.g.e. ) knot to attach a leader with a loop to a fly line without a loop. It uses very little of the end of the fly line, probably less than a half inch, and will stand up to time and stress for a very long time. So much easier than a blood knot, tied without tools under just about any condition with enough light to see what one is doing, and small enough to come back through the guides without an issue.
That being said, it doesn't work with some fly lines, at least on the Class 2 full sinking line I use for streamer fishing and probably other such lines.
