Secret Agent (4007); Concealable Boot Knife with Strong Single Edge 4.4 Inch 8Cr13MoV Steel Blade; Arrives with Dual Carry Molded Sheath and Stealthy Non-Reflective Black Oxide Finish, 3 OZ

The Kershaw Secret Agent is a discreet and capable tool that seems to vanish until it's needed. It's designed for those moments when a larger knife isn't practical, but reliability is still paramount. The 4.4-inch 8Cr13MoV steel blade, with its single edge and non-reflective black oxide finish, offers a balance of strength and subtlety. It’s sharp out of the box and ready to tackle a variety of tasks, from cutting cordage to preparing kindling.The included molded sheath is well-thought-out, providing secure retention while allowing for multiple carry options. Whether discreetly tucked into a boot or attached to a belt, the Secret Agent remains comfortably out of sight until called upon. Weighing in at a mere 3 ounces, it's a featherlight addition to your everyday carry kit that won't weigh you down.This knife isn’t about flashy looks or unnecessary features; it's about dependable performance in a compact and concealable package. For those who value preparedness and appreciate the utility of a well-crafted blade, the Kershaw Secret Agent is a worthy addition to their collection.

This thing is great! A small but mighty fixed blade knife. It’s just big enough to be a useful tool while at the same time being small enough to find a home on a plate carrier ,duty belt or load bearing setup without looking like Rambo’s goofy step son. Its easy to get razor sharp the clip on the sheath is stout. For those of you with knife skills its balanced extremely well and the black finish makes it invaluable in the right hands.The best part about it is it’s a fair price. Unlike some of those overpriced prison shanks out there.

Grip is good, knife itself is good, and for the MOST part, the sheath is good. The sheath retention is too strong though for the clip. As in going to draw the knife off of my belt or boot, the whole sheath comes with it. Gotta try and find a way to work around it and get it to stay on my boot. The knife itself I give 5 stars. The sheath I'll give 3.7.

I bought the Smith & Wesson SWHRT3BF and liked it so much that I bought the Kersha Secret Agent. Bad ass, buy one...you won’t be disappointed. If nothing else it’s a great addition to a collection or just cool to look at. It’s not really a great camp or dive knife. Also they should have given a better breakdown of the size. That’s the first thing I look for, so here ya go.....the handle is 4.25” including thumb guard..the blade is 4.25” with 4” of actual sharp blade. Sharp on one side only. You can always sharpen the other side. Feels great in my hand. Great case with a metal belt or boot clip. The clip can be removed and the case can be mounted horizontal with a little Velcro. It’s lightweight, compact and only good for one thing. Mine came sharp but that’s never a concern to me, because I always sharpen my knives as soon as I get them. Hope this helps!

I love this knife, and I keep it in my left boot everyday I wear them. It doesn't hold an edge all that well, but that's because it is a concealable self-defense knife designed primarily for stabbing and thrusting. That said, it does come razor sharp, and it's made of high quality steel so I bet if you sat down and took the time with it you could put a long lasting edge on this blade. I've bought three of these knives, two as gifts for family members and one that I kept for myself, and all three knives have held up immaculately after months of use. The sheathe this knife comes with is very nice, and is so slim that you can easily tuck it into a boot or pant leg. The handle feels great in the hand, and the knife handle isn't too big or too small, fitting nearly perfectly in my very average sized adult male hand. The blade feels very sturdy under pressure. I have no doubts that this thing could save your life in a pinch.

Very nice, sharp, and great price.

It's a nice knife, but don't expect it to be sharp when you get it. The one they sent me was about as sharp as a butterknife.

I've had the CRKT Dragon as my primary boot knife for a while. The Kershaw 4007 secret agent seemed lighter so I thought I'd give that a try. I found some important difference which skewed my decision back in the Dragons favor:Pros:The kydex sheath on the Kershaw 4007 is about 1/2 the width of the CRKT and the whole set up is lighter. In addition, while I found the handle of the CRKT Dragon excellent in a natural grip, it was not as good in a reverse (ice pick) grip. The Kershaw feels comfortable in any type of grip. I also liked the double-sided blade of the Kershaw as it penetrates effortlessly and a little more efficiently than the Dragon does.Cons:The kydex sheath on the Kershaw killed it for me. It's well built and holds the blade securely, however the design of it makes is UNCOMFORTABLE for long periods of time the way I carry it (upside down on the inside front of my calf with the metal clip REMOVED). Unfortunately while thinner than the CRKT Dragon's sheath, it is THICKER in an awkward manner that causes part of the sheath to dig into my calf after a period of time. The CRKT's sheath is much flatter and wider and sits more comfortably against the leg. In fact, I've worn the CRKT Dragon for an entire day without hardly noticing it was there. I couldn't wear the Kershaw more than 2 or 3 hours, which means I wouldn't carry it on a regular basis negating the entire benefit of having one. I tried the Kershaw as a forearm carry but it was too long for that and also had the problem of digging into me, and it's too long to practically conceal when clipped on my belt.One additional con is that, while the CRKT Dragon is most visibly full-tang, I have no reason to be believe that the secret agent is. In fact, the handle feels far too light to be full tang despite the butt cap that makes it APPEAR full tang. Similar in size to the Dragon, it was much lighter and the only way to shed weight is to shed metal like Kershaw did on the 4007...not what I really want to see in a backup knife.Bottom line: for my style of carry, the CRKT Dragon is a better fit for my needs though the Kershaw 4007 is a quality product.
