The Davy Knot

How come I have never seen this knot? If it has the same strength as a clinch knot well then I could see this becoming my go to. I have certainly used figure eight knots when fishing salt water and loop knots when fishing streamers but the Davy Knot just opened a new door for all of us fishermen out there. While many anglers are super efficient at tying clinch knots the appeal of this knot is the amount of tippet you could save as well as the size. The Davy knot appears to finish out at nearly half the size of a clinch knot making it an ideal way to attach flies in very clear slow moving water. I have to give this knot a try. Any of you Colorado Anglers out there using the Davy Knot?
