I am building a fixed blade with stacked leather handle. The pommel is 440C stainless steel, is 0.410" thick and has 0.393" of solid metal between the tang nut hole and OD of the pommel. I am considering adding a lanyard hole (I would be interested in your thoughts). I plan to use either 550 or 750 paracord, both of which are 0.16" diameter. I'm wondering if some of you more experienced 'KnifeDogs' could recommend a diameter for the lanyard hole? I don't plan to use any tubing. I have seen recommendations for 0.25", but that seems like it would be too large, IMHO. Your thoughts would be appreciated. Thanks!
