SP12SBK2: C12SBK2 Matriarch 2
History and Lineage

The Matriarch 2 traces its lineage to one of Spyderco's oldest and most unique designs; the C12 Civilian. The Civilian was developed in response to a request from a U.S. federal law enforcement agency whose agents were regularly involved in undercover narcotics operations. In many cases, their undercover status made it impossible for them to carry firearms, so they wanted a knife that could serve as a potent defensive weapon when wielded with gross motor skills and a minimum of training. Spyderco's founder, Sal Glesser, designed the original Civilian to meet this need and in the process earned a patent on its distinctive Reverse "S" edge profile. The sinuous edge shape maximizes the cutting potential of the blade by forcing the material being cut to move longitudinally along the curves of the edge as pressure is applied with the blade.

The Civilian design evolved over the years, but as a limited-production item and one of the world's most visually dramatic folding knives, it always attracted great interest. In the late 1990's, Spyderco's South African distributor requested a more economical version of the Civilian. Due to the high crime rate in South Africa, he felt it would be an ideal personal-defense tool. Spyderco responded by mating a Civilian-style blade to the fiberglass-reinforced nylon (FRN) handle of the popular Endura model. The result was the first Matriarch and yet another "instant classic."

The original Matriarch was produced with both gray and black handle for several years before being discontinued. In 2010, a flat-ground, brown-handled "sprint" run (a limited one-time production run of a particular variant) of the Matriarch was produced, once again igniting interest in the design an prompting its return as a regular production model: the Matriarch 2.

Construction and Materials

The Matriarch 2 is built on the handle of Spyderco's extremely popular Endura 4 design. Its full skeletonized stainless steel liners provide an outstanding balance of strength and lightweight, while its injection-molded FRN handle boasts Bi-Directional Texturing for a superior grip in even the most demanding conditions. A sturdy back lock mechanism locks the blade securely in the open position and a Boye dent in the lock bar helps prevent unintentional lock release. Screw-together construction and phosphor-bronze washers ensure maximum precision and smooth operation.

The blade of the Matriarch 2 is hollow ground from VG-10 stainless steel and features the signature Reverse "S" edge profile of the classic Civilian, which is designed to maximize cutting performance with all areas of its edge. It's point is thicker than the Civilian for increased strength and strategically shaped to nest discreetly into the handle in the closed position. A trademark Spyderco Round Hole provides positive one-handed deployment of the blade with either hand, ensuring that the user can get the knife into action quickly and reliably.

The Matriarch 2 also offers unmatched versatility with regard to carry options. Its four-position hourglass clip is adjustable for left or right-side tip-up or tip-down carry. Together with the lock operation and blade hole, this feature makes the Matriarch 2 completely ambidextrous and an ideal choice for left-handed users or armed professionals who prefer support-side carry on their knives.

The Matriarch 2 combines the unique heritage of the Spyderco Civilian family with the proven design features and economical construction of the best-selling Endura 4. The result is a knife that offers powerhouse cutting performance in a practical everyday-carry format.

Strictly self defense.
Chance are you're familiar with Spyderco, their combination of quality at an affordable price, innovative design and ease of use is why you probably already own one of their knives. In terms of build and materials the Matriarch 2 continues along these lines. VG10 is an outstanding steel and the fibreglass reinforced nylon handle is lightweight but textured enough to prevent slips. The design is where this knife veers away from the EDC knives that Spyderco does so well. Firstly if you're used to a dragonfly size knife you'll be surprised at the size of the Matriarch, obviously Knifecenter lists the length but I was still surprised to see how much room the handle provides. Secondly (and perhaps most importantly) the blade - it's aggressively curves forward towards the tip and is features Spyderco's serrations down almost it's entire length. Unless you saw rope for a living I'm not sure why you would EDC this knife, there are better knives out there for that, but if you want to carry a knife for self defense and want something unobtrusive the Matriarch 2 is perfect. You don't notice it in your pocket, it's well built, and although I thankfully haven't had to use it for it's designed purpose - I'm certain it won't let me down if that day comes.

The Matriarch2 is truly the Queen Bee of self defense!
Spyderco has taken their original design of the Citizen and thickened the blade w/ with a razor seration in a way that still retains the lightness of a feather. The clip will meet anyone's needs whether left or right handed, or prefer to open it quickly by the patented Spyderco thumb hole, tip up or down. A fine grip with a Web like pattern, and the Spyderco seal in the center of both sides of the handle. Bottom line, this blade is a beast. Her tip is very fine, able to peirce through all layers of clothing, and once she penitrates, this hawk billish blade will follow though as deep as the offender deserves, especially on the down stroke. Intimidation is not a big enough word when describing the Matriarch. A deadly, functional knife that won't stop slicing until you do. No tactical training is required to use this model, but be careful when you are figuring out what feels good while handling... you will get bitten if you aren't careful. Spyderco does it yet once more. Do some research on the Citizen, the model that the Matriarch2 was based on. A great history, a great knife, and a stellar company. I'very had to rely on them and their products many times and haven't been let down once. The warranty and repair department can and will help you in anyway possible, providing you don'the use you knife for anything else but what it was designed for. Take care of a Spyderco knife, and it will assuredly take care of you.

Not an everyman's knife
Let's be honest I don't carry this knife on me always, nor do I carry it as an everyday carry. As an EDC I carry a bright yellow spydie dragonfly, a nice and people friendly knife. But this one I tend to have around me, when stuff can go sour or goes sour. It doesn't as much cut as it rips. So it is excellent for rope, wire and clothing ( and because of the upswept tip, it can be used as an EMT knife, which is the way I use it in a professional capacity ). But it has bit me once of twice. It's a very unforgiving knife (even more so in the sprint brown version, I tend to think). So if you are planning on buying this knife, think twice. If you are a collector, it's quite a striking knife, buy it. If you work in emergencies, it can be a lot of help, buy it. If you are looking for a martial arts knife that will adapt to about any style, buy it. But if you don't belong to the previous categories, I don't see how this knife will help you. Buy something more people friendly. Yours sincerely
