Böhler N690 Steel Knives

Bohler N690 steel is a corrosion-resistant steel alloyed with cobalt. The steel producer is the Austrian metallurgical concern Bohler-Uddeholm AG. Steel N690 can be hardened to 60-62 RHC. Bohler N690 steel knives do not rust for a long time and remain resistant to various loads, which is especially important for tactical knives and survival knives. Therefore, such manufacturers as Extrema Ratio, Boker and others make knives from Bohler N690 steel. Bohler N690 steel knives are easy to sharpen.

Folding knife Böker Club Gentleman 6.4cm 110909
The traditional Böker Club Gentleman folding knife is the elegant brother of the famous Böker Sports Knife, known in North America as the Camp Knife. While the dimensions are almost the same, this knife has a more continuous shape, uninterrupted by tool cutouts. The typical metal bail for attaching a knife chain is also missing from the Club Knife.
The tang of this new version of the historic gentleman's knife is brass, while the decorative bolsters consist of nickel silver with a delicately milled groove. The handle scales are made from attractively patterned desert ironwood (certified import). The historic blade design is shaped from N690 and doesn't lock. The long nail nick, also known as a long pull, is equipped with fine teeth, perfect for striking suitable matches. The fully handcrafted slipjoint knife made by Boker Manufactory Solingen comes with the new version of the historic Böker tree symbol. Club Gentleman folder weighs 66 g.

Folding knife Extrema Ratio T-Razor Black 04.1000.0138/BLK 10cm - 4
Sold out
Folding knife Extrema Ratio T-Razor Black 10cm 0410000138BLK
Extrema Ratio T-Razor with black coating. Up to the early 1900s, people commonly carried pocket utility knives. Due to rampant “misuse”, though, laws were passed to the effect that all such knives were to be clipped at the blade-tip, in order to diminish their dangerousness as weapons. Some people then figured they’d get the greatest effectiveness out of the sharp edge of a traditionally flat-point blade shape, and took to carrying straight-razors. Thus, the straight-razor was for a time regarded as a fearsome weapon of self-defense. Such a “misuse” of the common straight-razor inspired our T-RAZOR design. Available versions: T-RAZOR BLACK, T-RAZOR SATIN.

Dagger Böker MG-42 121507 13.3cm
Sold out
Fixed blade Knife Böker MG-42 13.3cm 121507
The classically elegant Böker MG-42 121506DAM is the crowning achievement of historic projects. The blade is made of N690 and is ground off on both sides, while the dagger's toggle and pommel are made of solid stainless steel. The pommel incorporates the cooling fins and gas outlets of the recoil amplifier (actually a combined component with the functions of recoil amplifier, flash hider and barrel guide sleeve) as a design element. Nevertheless, here too, form followed function, for the grooves increase the grip of the dagger in the reverse grip. The toggle and pommel seamlessly hold the barrel-shaped roll of oak, which automatically centres itself in the hand due to its shape. The dagger is equipped with a high-quality sheath made of dark brown leather with belt loop and place reinforcement. Handmade in the Boker Manufactory in Solingen. Raw materials and production time had increasingly become critical and decisive factors in the course of the Second World War. Therefore, the Army Ordnance Office was looking for a successor to the MG-34, which was already convincing in its function, but took up too much time and material due to its complex production. Almost trouble-free function and firing accuracy in all weather conditions, the change of hot-fired barrels within seconds and a cadence of 1,500 rounds per minute (25 rounds/second) established the reputation of the newly developed and optimised MG-42. In a slightly modified form, the MG-42 is still the standard MG of the German army today as MG 3. Rare originals from the Second World War fetch between USD 40,000 and 60,000 at Rock Island Auctions.
