Kershaw Skyline, USA Old Timer small stockman, and Leatherman Kick are on me 99% of my waking hours. Sometimes I also carry a larger folder like my Kershaw JYD II, but most times if I need a larger blade, I grab a fixed blade.
I think the Skyline is one of the most underrated blade out there.. I've had mine for about 13 months to be exact, absolutely cant say enough good things about it..I've put that thing through it bigtime, cut asphalt shingles, lead roof jacks, heavy felt, cardboard, rope, zip ties, things I cant remember its surely a user...
If working construction its my skyline, or persistance.
regular life

I use a few Delica's (my personal favorite pocket knife)
or on occasion I carry a 1970 Puma Junior slippy..
oh, and lately a sog flashII..
oh, oh, but mostly I carry a hest so the pocket knife thing kinda comes and goes nowadays...................................
oh, oh, oh.. izzy on the neck,
oh, oh, oh, oh... coming sooooooon..... bk14 on the neck once I get around to the hobby store.. I have some ideas.........
oh, oh, oh, oh, oh....... always a vic sak classic on the keys.... and a leatherman juice on the belt..........................................................................
