Nice looking knives. I too am a fan of Ranger knives and Justin's work. There could not be a better custom maker to work with on the planet. When Justin gives you a time and date, you can bet you a## on it being ready on or before that time. That is a rarity among knife makers.
Is the 3/8" thick Ranger you posted a slightly modified TFI? I have one of his TFIs and love it, as well as all of his RD series blades.
