One last image. This is my current EDC, at least in terms of knives and firearms. The three knives one the left are carried every day, while the two to the right are optional carry -- one at a time -- depending on attire and where I'm going.
At the bottom left is a blade purchased from Jantz Supply years ago. Blades for knifemaking are often outstanding values and sometimes require nothing more than a simple paracord wrap -- or not -- and a good sheath. This knife is on my keys every day. It's quickly available: the corner of the sheath is hooked on the pocket when I draw the knife, and the weight of the keys helps keep the sheath in the pocket. I modded this blade to remove a serrated back edge and change it to a skinner shape. The connector allows the keys to be drawn without the knife. A SwissTech Utili-Key is on the keys and is my most frequently used knife, especially in an office environment. This setup works for me!
Center left is my most frequent neck knife: the CRKT Ringer 3. It's a great little blade for small tasks when I'm seated. I usually reach between two shirt buttons to draw it. I've used it several times in group settings where no one ever saw it. It disappears in my hand, and the draw is subtle.
Top left is a Blackhawk! HawkPoint folder. At less than $20, I consider it a great value. It's a framelock, and the lockup is very, very solid, with no blade play. It has opened many packages, and beverages (no alcohol for me while armed, however), and it's small enough that it doesn't alarm most people if they see me use it.
On the right are two TOPS knives. I carry one or the other when I can. The skinny one is a Rocky Mountain Spike, and carries easily in its pouch type sheath, behind my left hip, with part of the sheath in my back pocket. It's fairly new to me, but I like it a lot so far. I carry it frequently, but not to the office. The other is a TOPS Travelin Man 2, and I carry it occasionally, with my belt through its static line, and the sheathed knife tucked in my waistband, in front of my body, behind my cell phone. If I wear a dark, tucked-in shirt, the knife is not very visible at all, and no one notices it. It's extremely sturdy and is about the biggest, heaviest knife that I can carry all day in complete comfort.
As you can see, I like all-steel knives, because they are easy to keep clean and free of rust. Most of my EDC knives have seen use in food preparation when needed. The TOPS Travelin Man 2 became a full-time kitchen knife during a recent trip to Dallas. The place we stayed had not one usable kitchen knife (the few we found were cheap junk, and as sharp as marbles), regardless of what had been promised.
All my best,
Dirty Bob
