I've never posted pics here and would not know where to start, so I'll have to expalin what I see. Take a raw AL, and whatever size steel cable is on the lanyard Rob Supplies. essentailly remove half the aluminum thickness on the backside of the flashlight, the built inset retainer ring on the tailcap.
When on keychain, the lanyard acts as a saw/sandpaper to grind away at the aluminum till it gets thin enough to break or be foolish to leave on the lanyard and break and lose the flashlight. I have tried to EDC the raw in my pocket, and I end up using it and tranferring the light to another pocket or jacket pocket, and I end up searching for it. I have went back to the V5 buckle light for keys for now, as searching for the raw has drivin me crazy.
