I'm a chronic pocket knife carrier, so I have to be really careful to stash my knife somewhere safe any time I have to go through security whether it's the Emergency Room, the airport, or some event with security, which tends to be most events these days. I've actually buried my knife in a landscaped plant and dug it up later to keep from having it confiscated. When I went to the state fair, they took it but gave it back on the way out, amazingly. So my favorite is probably my Lagiole with a wood handle and carbon steel blade, with one blade and no lock. But both because of its size, a little large for everyday, for years I've carried a little faux bone handle New York made Camillus, an outfit that made surgical steel medical implements during the world wars as well as knives. It is near Syracuse, and though it went out of business years ago, I think it may have been revived. It has a Hornet 22 cartridge end embedded in the handle, one blade with a lock. It is the usual stainless steel, but for the last 25 years, truly durable. I don't have a big collection, but probably six or eight others. My wife and I also have a Lagiole cheese knife. I bought my pocket knife in the provinces in France, and I think the cheese knife was acquired in France years before that.
