The Chris Reeve CGG “Think Twice Code” Large Sebenza 21 Folding Knife
Chris Reeve Knives is a production knife manufacturer. As a production company, they design and produce their own knives, as opposed to a custom knife maker who will work with a client to design or bring his or her knife idea to life. All of their knives are produced in a combination of hand and machine work out of their shop in Boise, Idaho.
They say, “Chris has always ‘pushed the envelope’. Whether on a motorcycle or behind a belt grinder, he dreamed of being a world champion. He did not win a motorcycle world championship but in many respects, the standing of CRK today represents one. His induction into the Cutlery Hall of Fame in June 2015 could be considered his championship trophy. The single thought in Chris' mind has always been to design every model with deliberation, taking into account how the knife works, its intended purpose and the most appropriate materials. On this foundation, CRK is a vibrant business, has a great staff of well-trained employees, and remains a company with a worldwide reputation for raising the standards bar – ‘pushing the envelope’ - for the industry.”
Today we’re going to look at the Large Sebenza 21 that has been finished with the CGG “Think Twice Code” image on the handle. This knife is currently in stock at BladeOps.
The blade on this knife is made out of CPM S35VN stainless steel. This steel was designed by Crucible, in collaboration with Chris Reeve, which makes it no surprise that it is used on this Chris Reeve knife. The two got together to make a steel that was similar to S30V steel, but with some major improvements. S30V steel was known for having very high corrosion resistance levels. It was also known for having the perfect balance between hardness, toughness, and edge retention, which is a harder combination to achieve than it seems. This is because the harder the steel is, the less tough that it is going to be. S30V steel had created one of the best balances between these two characteristics. However, because the steel was so hard, it proved complicated to machine or to sharpen. This is what Chris and Crucible decided to fix. They started with a similar formula, but this time, they used a finer steel structure. They also added a little bit of niobium into the steel matrix, which brings out the hardness but makes it easy to sharpen still. This steel is going to still have the best characteristics that the original version of the still did, but it is definitely improved. When it comes to such a high-end knife, such as this one, you are only going to want the best steel. On the Think Twice Code Sebenza, you are getting the best steel.
The blade on this knife has been stonewashed finished. This finish is a nice finish because it prolongs the original look of the blade overtime. It is able to do this because the rugged texture look easily conceals scratches and smudges that are going to occur with use and time. The rugged texture look is accomplished when the blade is
tumbled around with an abrasive material, which is most commonly small ceramic pebbles. The pebbles rough up the steel, then the steel is removed, smoothed out, and polished. The stonewashed finish that this blade has is a subtler stonewash finish, which does mean that it has a little bit of a sleeker look. The subtle stonewash goes well with the “bank vault” feel that the handle creates. This also makes the blade the ideal option for a tactical knife, as you won’t have to worry about the beating that the blade is going to take.
The blade on this knife has been carved into a drop point style blade, which is the most common blade shape that you are going to come across in today’s cutlery industry. This is for a few reasons including that it is versatile and tough. The blade has a spine that slowly and shallowly curves from the handle to the tip of the knife. This slight curve does create a lowered point, which is one of the first meaningful characteristics on the blade shape. The lowered point is going to allow you to have more control when you are using this knife. You will be able to perform fine detail work with this knife because of the lowered point.
The other big feature of the tip is that it is a very broad tip. This broadness is where you get the high strength that you have come to expect from this blade shape. The strength of this blade shape is nearly unmatched, and you won’t have to worry about taking on tougher tasks, because this blade is not going to break easily. The broad tip is even enhanced by the high-end steel that the Large Sebenza 21 sports.
The last reason that the drop point blade is loved by many is that it has a very large belly that allows you to easily slice through almost anything. The steel can also get to a razor-sharp edge, which will enhance the belly perfectly. The drop point style blade really only has one major disadvantage: the broad tip. This is funny, because the broad tip gives the knife so much strength, but it actually also takes away some of your piercing capabilities.
The handle on this knife is made out of 6AI4V Titanium. Titanium is known as being very similar to aluminum, except that between the two it is the superior metal. Titanium is a lightweight metal alloy, just like aluminum. Titanium is the heavier between the two metals, but with the extra weight, you get incredible strength. Although it is considered to be the heavier of the two metals, Titanium is not hard—it is definitely still a lightweight metal that will keep the overall weight of the knife down. However, because it is stronger, it is harder to machine, which also means that it is going to be more expensive to machine. Out of all the metals, this titanium is going to give you some of the best rust resistance.
Titanium differs from aluminum because it actually has a warm feel to it instead of having high conductive properties. This isn’t going to make that big of a difference if you are using this knife in a warm environment. However, if you plan on using this knife in cooler environments, this is a big advantage.
Titanium is going to be prone to scratches, which is a drawback. The Large Sebenza’s back handle scale has been finished with a matte grey anodization, which will prevent some of the scratches, but definitely not all of them.
The front handle scale has been finished with a special CGG (Computer Generated Graphic) of a “Think Twice Code” graphic. This is achieved with CAD/CAM software and then transferred to a CNC machine for milling and finally is PVD coated.
This graphic is set on the matte darker grey base of the handle. Then, going across the width of the handle, there are various widths of stripes that are in a brighter silver. The stripes also have various distances between them.
The handle itself is simple, which is necessary when the pattern of the handle is going to steal the show. The spine is nearly completely straight from the top to the butt. The butt flares out ever so slightly and isn’t completely rounded. The butt does have a few angles that create the shape of it. The belly of the handle sports a smaller finger guard that will protect your fingers from some accidental slicing. Of course, with a knife like this, you probably won’t be needing too large of a finger guard. There is no thumb groove, but there is a slight thumb indent. This will help a little bit with grip, because it will add a bit of texture. There is a braided, black lanyard that comes attached to the handle of this Large Sebenza 21.
The Pocket Clip:
The pocket clip is statically designed or tip up carry only on the traditional side of the handle. It is made out of titanium, which is known for being durable, but also a little bit springy. This allows you to keep stretching it onto your pocket without worrying about any damage. The clip is kept in place by a silver screw, which does match the rest of the hardware on this knife.
This is a manual knife that has been equipped with a thumb stud as well as an Integral Lock frame lock design that was built to handle a lifetime of use and abuse.
Because this is a manual knife, it is going to be legal in more states and cities than an automatic knife. However, you do still need to know your local knife laws before purchasing this knife and especially before carrying the knife. While the manual knife is going to be legal in more areas, it is also not going to be as smooth or as quick to bring into play.
The thumb stud is a very common opening mechanism, especially for manual folding knives. It is a small stud that sits near where the blade begins and the handle ends. This stud allows you to push against it with your thumb, which is going to swing your knife open before locking it into place. There are some obvious advantages to a knife having a thumbstud. The first is that it is super easy to get the hang of as well as being easy to use. Also, the thumb stud allows you to open the knife with only one hand, which is ideal for complicated tasks that require two hands or your full attention. There are a couple disadvantages. The first is that some people don’t like how the stud extends off the blade, because they feel like it gets in the way when they are trying to use the knife. The second is that the thumb stud does put your fingers in the path of the blade when you are opening it. There have been many cases of people accidentally cutting themselves when they were opening a knife with a thumb stud. It shouldn’t be a huge problem, just be careful as you first get the hang of this knife.
The blade on this Chris Reeve measures in at 3.625 inches long with a handle that measures in at 4.71 inches long. This means that the overall length of the knife is going to measure in at 8.335 inches long when the blade has been deployed. The knife weighs in at 4.7 ounces, which is an ideal weight. It gives you the heft that you need without weighing you down. This knife was made in the United States of America.
The Chris Reeve Sebenza has become synonymous world-wide with quality, rock solid performance and a "bank vault" feel. First developed in 1987, the Sebenza has gone through only some minor changes over the years and in 2008, the Sebenza 21 was released to celebrate 21 years of this flagship model. This model features an Integral Lock® frame lock design that was built to handle a lifetime of use and abuse and each premium stainless-steel blade is deployed with the single thumb lug. The special CGG (Computer Generated Graphic) "Think Twice Code" graphic is achieved with CAD/CAM software and then transferred to a CNC machine for milling and finally is PVD coated. This larger model boasts a titanium handle, a drop point style blade in a tumbled stonewash finish and the titanium pocket clip is statically designed for tip up carry only on the traditional side of the handle.
