Many of my knives have lanyard holes, and as a hobby knife maker (not really make, complete from kits), I usually include lanyard tubing, but the only one of my knives that actually has a lanyard on it all the time is my Randall #5. I have never felt the need to actually use it, but I leave it on, just in case. If wandering thru thick brush I usually tuck the lanyard under my belt as some added insurance against loss...
