I picked up a 15 inch 20 ounce satisal wood handle Ang Khola by Amtrak Kami from 1/25 Knife Clearance and took it out today for some small clearing of some 3'' trees that were in the way and after about 30 mins of work I was done and went to clean the kukuri and noticed it now rattles slightly. Everything apears to be tight but you can slightly hear the rattle and feel it when you move it back and forth. Does anyone know what I can do to fix this?
