My First Case XX Knife Purchase !!

So I stopped by Yates Hardware and scooped up a RussLock. I know it's not the most popular of the Case XX Knives and I can understand why but I'm excited to check it out. gonna try to carry this knife for the entire month of October. Not sure if my spoiled butt will maje it but we are gonna give it a go. This isn't a slip joint is it?
