I always have a knife on me, usually two, except where security won't permit like courthouses airports etc....
Normally, my defense knife is a lockback blade with a thumb post for one handed easy opening, but I am looking for a new one due to the old one wearing out.
I am carrying another lock back type for self defense but do not like it much as it requires two hands to open....
Currently I also have an Old Timer twin bladed knife that was my dads. But the blades dont lock back so I only use it as a pocket knife for opening boxes,envelopes and the like. it does stay nice and sharp as it still has carbon steel blades that hold a good edge!
I carry a Kershaw Blackout as my defense knife and a Buck Odyssy for my workhorse. I love the assisted open feature on the Kershaw, since I can't carry my Boker Top Lock II. I also keep an old Ka-Bar USMC in the trunk for whatever it may be needed for.
The muzzle end of a .45 acp says "Go away" in pretty much every language.
I carry and old lockblade knife that has a leather pouch for it. It is rusty looking but deadly sharp. Works good. My other knives which i carry often are just some knives without name brands. I like to carry a 9 inch fixed blade in my bags when going to places and in my truck. Got a Winchester multi-tool knife that gets a little big to carry around but works great in all situations. Never know what you will need. And as usual, I lose them all the time. Either they fall out of the pocket or I leave them in a hay bale when cutting strings.
