Kershaw 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

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.

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!

For the price, it's certainly hard to miss up. Let's do a quick review.Pro's:-Rubberized, fat in the middle handle. This is how a knife handle should be - the tried and true method of preventing your hand from slipping up, is to make it fat in the center of your hand. The width where the hand-guard would be is small, yet adequate.-The profile is good, and follows the traditional fairbairn-sykes idea - nothing to intrude with the penetration of the knife.-The price is right.-The sheathe is well-made, but has some downsides. More on that later.-The finish is decent, and may be a negative for some. But if you like your knife to show some wear after you've put it through the paces, this is great.-I personally like the steel, it's a little softer than AUS-8 but it sharpens very quickly and you can put a very sharp edge on it.-No blade wiggle in the sheathe.Con's:-Manufacturing lines, and the screws are very obvious.-The sheathe makes it difficult to mount a different kind of clip onto it - there was no uniform idea for the hole spacing on it's edges to put a different sheathe on with it.-The biggest con is that it advertises as a double-edged, but only one side is sharpened. I had to manually grind the other side down into a sharp edge - that should be stated on the box that this is the "updated" design and is only single-edged.- The con of the steel is that it doesn't retain sharpness for long. Considering this isn't really a utilitarian knife, and is more for very specific duties that the utility knife can't or might struggle to do, then edge retention isn't as big of a priority. It IS a chinese steel, but it's one of the best chinese steels you can get. You won't be confusing it for Elmax any time soon, though.-Didn't come sharp out of the box. This is a stupidly easy thing for the company to do, and no one minds spending an extra dollar to pay the quality control guy to do his damn job. Kershaw is usually great about this, but this is the first one that didn't come with a great edge on it already. You may have a different experience.

Fun knife! :)

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.
