While likely included as Spyderco’s trademark “spider hole,” it also serves some obvious functions. One option is to use the hole in tandem with the lanyard hole to tie the knife to a branch making a fine spear. Or you could use paracord to secure the blade sharp-side out onto a branch or tree trunk.' (Spyderco Bushcraft review, JFGI)Gee I dont know, maybe the hole is there to fit all your knife knowledge in there, since its obviously a normal thing on a lot more expensive and well known knives.
