I just got my USAF Survival/Pilots knife (Ontario 2-80) from an E-bay purchase today. Nice conddition, aside from a slight gap/space between the leather washer and the hex end of handle. VERY slight movement, just enough to annoy me. I suspect the leather dried out and shrunk a wee bit, causing the space, almost enough to slip a piece of paper into. How do I fix this? I though about putting a little super glue into the gap, to retighten it. What would you guys suggest????? Thanks!!!
