Product Description

Böker Manufaktur Solingen Trapper Uno

In the world of knives, tradition and modern style don't have to be mutually exclusive. On the contrary, there has been a palpable trend in the knife industry to take timeless classics and give them a deliberate redesign, updating them with a modern, contemporary appearance. At the same time, the basic concept of the knife must be respected. The idea of the so-called Modern Traditional is the basis of the knife series Boker Uno.

The styles Trapper and Delicate have been classics for more than a century, featuring in the product lines of renowned international makers of classic pocketknives. In their traditional form, both styles have top and bottom bolsters. The Uno series omits the bolsters on the handle butt, a modification that gave the series its name. The two styles are no longer seen as mere utility knives on the ranch or construction site, but also hold their own as high-end EDC knives in barber shops or at a picnic. We selected exclusive matching handle scales made from certified imported desert ironwood, which are riveted to the brass liners. The blades consist of 440C and do not lock. The fully handcrafted slipjoint knife made by Boker Manufactory Solingen comes with the new version of the historic Boker tree symbol.

While it was still a high-end steel several decades ago, 440 is a very decent middle-grade steel today. Many users still see it as the perfect "magical trifecta" of edge retention, corrosion resistance and easy sharpening. It is still the first choice for Boker Plus and for many models from our Solingen manufacture.

Desert Ironwood

Desert ironwood (Olneya tesota) is a type of fine wood used to make handle scales.

Desert ironwood is indigenous to the southwestern United States and the very northwest of Mexico, especially in the Sonora desert. It belongs to the Olneya genus, a member of the papilionaceae family. Desert ironwood grows as a shrub or tree. The plant can grow up to ten meters tall with a trunk diameter of approximately 60 centimeters. The gray bark of younger trees is smooth and develops cracks as the tree ages. Desert ironwood is an evergreen plant that can still cast off its leaves in sustained cold temperatures below 2°C or during a dry spell in order to reduce its water consumption.

Desert ironwood is very sensitive to frost and dies in cold temperatures of less than -9°C. The sapwood of desert ironwood is yellow and unsuitable for the production of handle scales. The heartwood presents a range of colors from delicate grayish brown to a rich dark brown hue. Sometimes, it is almost pure black. The wood has a striking pattern with a mottled or marbled look. Desert ironwood is relatively heavy, very hard and rather tough. Due to these properties is difficult to process but makes up for it by being rather resilient and weatherproof. Therefore, it is the perfect material for handle scales.

The wood can be finished with various wood oils, though it is not very absorbent. Desert ironwood is extremely rare and expensive. To protect the small tree population, only deadwood, i.e. the wood of fallen trees, can be processed legally. Apart from handles scales for knives, desert ironwood is also used for artisanal work such as carvings and inlays.

Nickel Silver

Nickel silver is the name of an alloy containing copper, nickel and zinc that has a silver-like look. In the knife industry, it is mainly used for fittings, especially for the so-called bolsters.

Nickel silver is an alloy of copper (45-70%), nickel (5-30%) and zinc (8-45%). In some cases, it can also contain lead, iron, manganese or pewter. Due to its nickel content, nickel silver is harder and more resistant to formation than pure copper, which makes it particularly suitable for knife fittings. Nickel silver can be work hardened (by forging and milling) at temperatures below 500°C. Nickel silver has several other names, some of which points to the history of the alloy, including argentan and packfong. The material is also known as German silver. The alloy originated in China, where it was known as packfong. In Europe, a copper/nickel/zinc alloy similar to packfong was developed in the late 18th century in Thuringia.

The material was improved simultaneously in Saxony and Berlin in the early 19th century. While the Saxon alloy was sold as argentan, the product from Berlin was named nickel silver. Both alloys had similar properties. Apart from these historic terms, the material is also known as alpacca. Its silvery white surface makes this alloy look like silver, but it is much less expensive than the precious metal. Right after the production process was developed, nickel silver was used to make silverware.

Today, nickel silver is still used in the industrial production of silverware, sometimes as a carrier material for silver-plated utensils. In the knife industry, nickel silver is used to make fittings. The crossguard of cutting and stabbing weapons is often made from this alloy.


The slipjoint is a locking mechanism for folding knives. Slipjoint knives do not possess a mechanical locking mechanism. Instead, the open blade is locked only by means of a spring attached to the end of the spine. 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.
