Product Description

The Boker Plus Credit Card Knife follows an unusual approach. With a length of 7.1 centimetres, a width of 3.5 centimetres and a thickness of just 3 millimetres, the closed knife disappears discreetly into your wallet, for example. Alternatively, this extremely lightweight can also be worn comfortably with a clip in the shirt pocket or with the ball chain as a neck knife. The plate is made of titanium and offers a robust and reliable locking with the Framelock. To reduce weight, the board and blade have milled slots. The finger grooves and the G10 handle end ensure successful ergonomics despite the flat design. The design by John Kubasek, the well-known knifemaker from Massachusetts, is based on a coated 440C blade. An extraordinary companion for everyday life and leisure time. With removable clip (tip-down).

John Kubasek

John Kubasek from Massachusetts is Knife Maker since 1988 and has specialized in Pocketknives with a liner lock over the years. But innovative mechanisms also belong to his designs, such as magnetic push buttons.

440C

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.

G10

G10 is a so-called glass fiber reinforced plastic (GRP for short) used for the mass production of handles but also for blades and even entire knives.

As a glass fiber reinforced plastic, G10 is a composite material. This type of material consists of at least two base materials. The special feature of composite materials is that the finished composite still retains the individual structures of the base materials. This means that the base materials also keep their own chemical and physical properties. Compared to traditional materials, composite materials are lighter and more durable.They were first used in those areas and industries in which weight reduction is a priority, such as aircraft or race car construction.

In recent years, however, composite materials have also been used for other products, including knives. The base materials used for G10 are glass fibers and epoxy resin. Glass fibers are produced by melting glass and extruding fine filaments from the melt. Glass fibers are highly resistant to chemical materials and physical influences, which makes them weatherproof and age-resistant. They are also incombustible. In addition, glass fibers possess a high tensile modulus, which means that they are relatively sturdy. Epoxy resin is a synthetic resin that can be cured to form a plastic material.

Cured epoxy resin is extremely hard and strong but at the same time considerably lighter than metals with comparable properties. To produce G10, a glass fiber matrix, i.e. a woven glass fiber structure, is embedded in epoxy resin. The two materials are shaped and cured together. The curing process permanently bonds the glass fiber matrix to the epoxy resin. The glass fibers make the resulting fiber/plastic composite very sturdy and durable, while the epoxy resin makes the material lightweight. Handles, blades or entire knives made from G10 are often black or charcoal gray; handles made from this material often have a rough surface.

Titanium

In the knife industry, titanium is not just used to make blades but also handle scales. The metallic white material offers several special properties. While pure titanium is rarely used in knife production these days, titanium alloys are still very popular for making high-quality knife handles.

Titanium is extremely strong and light and offers high corrosion and temperature resistance. The material is particularly corrosion-resistant because it creates a protective layer as soon as it touches oxygen. Under most conditions, this protective layer either shields the titanium from corrosion entirely or at least strongly inhibits corrosive effects. Although titanium is much lighter than steel, it is still very strong. In physics, the strength of an object describes its resistance to the impact of external forces without breaking. Temperatures above 400°C, however, make titanium lose much of its strength. Therefore, titanium alloys are mostly used in knife production. Alloys are metallic materials consisting of at least two different base materials. The titanium alloys used to make knives usually contains vanadium or aluminum, two elements which significantly increase the strength of titanium at high temperatures. The purity of a titanium alloy is denoted by its classification.

The classification devised by the international standards organization ASTM International is widely accepted around the world. It defines 35 grades of purity for titanium alloys, with the first four grades being reserved for pure titanium. If you are in the market for a knife with handles scales described as \"made from titanium\", you should check whether they were made from pure titanium or a titanium alloy, as some of these handles scales simply receive a titanium coating.

The coating usually hides another – and often less expensive – material that might peek through one day, if the titanium coating wears off with use. While pure titanium has become rare and can usually be recognized by its high price point, the difference between titanium alloys and titanium coatings is often not easily recognizable for non-experts.

Framelock

A framelock (also frame lock) is a special type of locking mechanism used in one-handed knives. Knives equipped with this mechanism are called framelock knives. The framelock closure system makes it possible to open and close a knife with one hand.

The main components of a frame lockknife are the riveted handle scales and the blade. One of the handle scales of a framelock knife has an L-shaped notch at the bottom that begins just below the front of the handle scale and runs across approximately two thirds of the handle length. The scale section partly separated by the notch is curved slightly inward.

The locking mechanism of a framelock works as follows: While the blade is closed, it is held back by the partly separated section of the handle scale, which exerts inward pressure. When the blade is opened, this part of the handle scale moves inward, locking the blade. Unlike the linerlock, which has a separate locking plate covered by the handle scales, the framelock is part of the handle itself.

The name of this locking mechanism is derived from its construction, because it is the frame that creates the lock. The handle scales of a framelock knife are usually made from particularly hard metals such as titanium or stainless steel, because these materials offer adequate resistance to the blade when the knife is used.
