Hello there! This is my first post, so please forgive me if I have broken any rules. If I have, I apologise in advance, please let me know what I've done wrong.  
Anyhow, the subject of my enquiry is this: 
Military Fix Type Closure 
My interest is the closure method. It is described as a 'Military Fix Type Closure' 
I have scoured the internet and my books on leatherwork, but to no avail. I don't even know what it's called, apart from their description given above. I have had some ideas as to how to make it, but since I am new to leatherwork, I'm sure you people with much more knowledge and experience would be able to set me on the right path. 
Essentially, I would like to know what it's called; ways to make it; its advantages and disadvantages; where to find-out more and so-on. 
Thanks, 
Chris
