I purchased an MOD survival knife to mod. One of the scales was a bit 'clicky' so i soaked it overnight in teak oil, no change so i cobbled together a punch and anvil after a few light taps the scale split. No dramas there but the holes in the tang are a fag paper over 5mm. I can source 5/16th corbys with a 5mm x 9mm shaft but are a bit pricey. The first Q is what max undersize of pin vs tang hole is acceptable ? As its going to be used for 'clobber time' as a complete novice i am reluctant to waste time, effort and my hard earned. Q Two, would non tightening pins hold up as another option ? Thanks, Jon
