Böker Solingen Barlow M4 Sherman-Damascus Folding Knife 2.44″ Clip Point Blade


The worldwide enthusiasm for our unique Boker M4 Sherman-Damascus quickly convinced us to also design a classic model supplied with the history-steeped Damascus steel. Compared to the original model, the traditional Boker Barlow is significantly more compact and not only cuts a particularly good figure in the knife showcase, but also impresses as a gentleman’s knife suitable for a trouser pocket in everyday life. The blade is made of the incomparable Sherman-Damascus, is opened by nail nick and does not lock. The operating safety of the history-laden slipjoint pocket knife is further enhanced by a 90 degree detent when opening and closing. The striking drop shape of the Barlow can be traced back to the English pocket knives of the 17th century, which certainly makes it one of the oldest models ever. The name of the classic probably goes back to an enterprising Sheffield knife manufacturer of the same name, who began exporting the robust knives to North America around 1800. There they immediately enjoyed great popularity and so at the end of the 19th century the first Barlow models also appeared in the history of the Boker Manufactory.

The American M4 Sherman was designed as early as 1940 and is still considered one of the most famous tanks in history. It was produced between 1942 and 1945, put into service until 1957 and used in all battlefields of the Second World War – not only by the United States and Canada, but also by Great Britain, the Free French Forces, China and even the Soviet Union. The Sherman was built almost 50,000 times and is the most frequently used tank by the Allies in the Second World War. It was produced in countless mission-specific variations and used well into the Cold War. Together with the Americans in the Wartime Museum in Virginia, we have managed to preserve an important piece of vanished history.

The Boker Barlow M4 Sherman-Damascus is supplied with a unique Damascus blade forged from various materials from the production of M4 Sherman tanks previously restored by the museum. The unique 80-layer Damascus is hand forged for us by Chad Nichols in the customized Ladder pattern and is reminiscent of the tank marks left in the ground by the heavy tracks of the M4 Sherman. The integrally constructed Barlow is supplied with burlap micarta handle scales that are colored to evoke the authentic camouflage finish of the U.S. Army and Marine Corps. The stainless steel handles are CNC-milled from the solid and also form the characteristic bolsters and are ground to a matt finish by hand. Supplied with a high-quality felt case for storage, a certificate of authenticity and an individual serial number. Handmade in the Boker Knife Manufactory in Solingen.


  • Damascus Steel Blade
    • Damascus is a composite steel, i.e. a steel made from two or more steel bases with different characteristics. The finished product has a clearly visible texture of alternating layers of its base materials. Two or more types of steel are used to make a composite in order to achieve a finished product that combines their strengths.
  • Nail Nick
    • The nail nick is a notch driven into the blade, which gives the thumbnail hold when opening the blade.

Additional Information:


Damascus steel is the name of a type of steel that was very popular in the Middle Ages and the Early Modern Age. It was named after the Syrian city of Damascus, a former trade center for knives and swords with this type of blade. Today, Damascus steel is rarely used but still appreciated for its decorative exterior.

Damascus steel was developed to compensate for the disadvantages of steel as a material in the production of swords, knives and other weapons. Using a hard or soft steel to make blades resulted in specific advantages and disadvantages: Blades made from hard steel are very strong and retain their edge for a long time, but they are also brittle and quick to break. Blades made from soft steel, on the other hand, don’t break but bend and lose their edge quickly.

The combination of hard and soft steel typical for Damascus results in a finished product that doesn’t break (like soft steel) while still offering good edge retention (like hard steel). The base materials of Damascus steel are usually welded together. The steel layers are forge-welded according to a basic principle: Finer layers of steel are better and easier to join. It is not unusual to weld several hundred layers for one blade.

Today, Damascus steel no longer plays a role in blade production due to the availability of mono steel products (made from one type of steel) offering the same properties achieved in Damascus steel by combining two or more steel types. Damascus steel is still appreciated for its decorative exterior and long history.

Nail Nick

Especially with classic pocket knives, the nail nick is a popular opening mechanism. It owes its name to the typical notch in the upper part of the front of the blade, into which the fingernail hooks to open the knife. During the manufacturing process, the notch, which is usually 1 – 1.5 cm long, is literally driven into the material. In classic American pocket knives, the nail nick occasionally extends as a long groove parallel to the back of the blade, which is also called “long pull” in the technical terminology. Due to its discreet appearance, this opening mechanism retains the elegant appearance of the knife without disturbing the appearance. Due to the necessity of opening the knife with both hands, knives with nail hammer are considered two-handed knives. If the folded blade offers the fingertips of thumb and index finger enough space for the so-called pincer grip, modern knives often do without the nail nick.


Slipjoints are one of the most common locking mechanisms for folding knives.

A slipjoint has a small spring at the back end of the spine that keeps the open blade in place. The knife is closed by putting pressure on the spine of the blade to overcome the resistance of the spring holding the blade in place. Once the spring no longer holds the blade, it can be closed very easily. Unlike other locking mechanisms, a slipjoint is not actually locking the blade, which means there is a heightened risk that the blade might close as it comes in contact with a hard object. For knives with this locking mechanism it is of vital importance that all parts are firmly and securely fitted together.

The slipjoint is regarded as the classic locking mechanism for folding knives. Before the other locking mechanisms were invented, e.g. the backlock or the linerlock, just about all folding knives were equipped with a slipjoint. This is the main reason why slipjoint knives remind many knife collectors of “grandpa’s pocketknife”. A pocketknife carried by people of our grandfathers’ generation would have had a simple slipjoint mechanism.

Folding knives with multiple blades are one of the main applications of slipjoints, because this locking mechanism allows for a parallel arrangement of several folding blades. Another major reason for the widespread use of slipjoints is the fact that many countries have strict rules and regulations for carrying one-handed knives with a locking blade. Here, knives with a slipjoint mechanism are a better – and legal – alternative.

Stainless Steel

Stainless steel is a name for different alloyed and unalloyed steel types with a particularly high degree of purity.

In metals and metallic materials, purity describes the number of inclusions of substances that might impact the performance properties of the material. Inclusions are created in the course of the material’s production process In steel production, inclusions happen during the smelting process in the furnace, through small amounts of incombustible materials getting into the steel melt (exogenous inclusions) or by means of the so-called deoxidation (endogenous inclusions). For the latter process, a deoxidation agent (such as aluminum waste) is added to the steel melt. It reacts with the oxygen contained in the steel melt, thus removing the oxygen and preventing air bubbles from forming in the steel. Large amounts of endogenous or exogenous inclusions are undesirable, because they have a negative impact on the performance properties of the steel.

Inclusions (such as aluminum or silicon) of stainless steel are removed from the steel melt either during the production process or with the subsequent heat treatment of the (firmed up) steel. For each material, the official bodies in charge of standardization have determined the maximum amount of remaining inclusions in order to denote a steel product as stainless steel. Within the European Union, stainless steel is defined by European Standard (EN) 10027-2, as enacted by the European Committee for Standardization (CEN). According to the standard, unalloyed stainless steel is marked with the steel group numbers (material numbers) 10 to 18, while alloyed stainless steel is associated with steel group numbers 20 to 89.

Although the name is commonly used, it is actually incorrect to equate high-grade steel with stainless steel (or rustproof steel). Not all high-grade steel is stainless, and not all stainless steel types are high-grade steel. The requirements for stainless steel are clearly defined and may be met by some high-grade steel types, even though this isn’t always the case.

CNC Machining

It was developed in the mid-1960s and has been used over the years to streamline serial and individual production by making the axles and tools move much faster while still achieving the same level of precision. Almost all modern, newly developed machine tools are equipped with CNC controls.

With the use of CNC machines, it has become possible to process complex shapes in two or three dimensions. The high speed and precision of the processing steps makes it possible to produce serial parts without human input. The repeat accuracy of this process is extremely high, which means that production variations can be almost eliminated.


Micarta is sturdy and lightweight, which makes it a popular material not just for exclusive knife handles but also for a variety of high-tech applications.

The fiber-plastic composite known today as Micarta was developed in 1910 by the American engineer George Westinghouse. Micarta is the original brand name given to the material by its US producer General Electric. Today, Micarta is a common term for similar fiber-plastic composites made by several manufacturers.

All of these composite materials have in common that they consist of at least two different base materials which are bonded together but retain their own structure. Therefore, composite materials combine the different properties of their base materials. They are usually developed to offer all the advantages of comparable conventional materials at a much lighter weight. That is why they are mainly used in high-tech applications where weight reduction is a priority (e.g. in aircraft or vehicle construction) but also where the use of light materials makes for easy and pleasant handling, e.g. in the production of high-quality knives.

Micarta has all the usual characteristics of composite materials. It is a combination of absorptive fibers (e.g. wood, linen or cellulose) and a synthetic resin (mainly epoxy or phenol resin). To make Micarta, the fibers are saturated with resin. When the resin is cured, the composite material can be processed, usually by grinding or sanding. Micarta is extremely dense and resilient. It also offers a high level of dimensional stability, which means that it retains its measurements even under changing environmental conditions, such as varying temperatures or humidity levels. Micarta is pleasant to the touch and offers a firm, comfortable grip. Like all other composite materials, it is very light compared to metals.
