The great success of the Boker M4 Sherman Damascus, which stems not only from the history of historic Damascus steel, but also from the design of the modern folder, has led us to use this as the basis for a leading and enjoyable EDC with a titanium frame that, despite the powder metallurgy of the blade, also carries the original M4 piece Sherman Damascus. the reason is considered "miracle steel. Unlike commonly used tool steels, this steel has been specially developed for the production of knives. The three desirable properties of the steel - edge retention, toughness and rust resistance (stainless in DIN category) - are a conflict of objectives To make the steel resistant to rust, the addition of chromium is necessary, which makes the structure rough, brittle and susceptible to cracking in under normal conditions High hardness, which has a positive effect on cut life and ductility, is usually achieved at the expense of toughness. Thanks to Magnacut, despite the high chromium content of 10.7% and the impressive hardenability of over 62 HRC, it was possible to obtain a very fine microstructure, and thus high strength and tolerance to shock loads. The addition of nitrogen plays a major role here. Nitrogen is actually a pest of steel in the alloy. However, due to, among other things, the advanced heat treatment, Magnacut nitrogen is integrated into the crystal lattice structure of the steel structure and thus achieves otherwise conflicting material properties. The main design difference from the M4 Model Damascus is the elegantly contoured fin which With a slight impulse, the blade comes out smoothly and encourages play. The ball bearing is alternately opened by a thumb stud and locked by a solid titanium frame with a stonewash finish. The overdrive limiter acts as a protection against overextending the bolt. A milled titanium clip (tip-up/r) with a steel ball and handle scales made of wild carbon fiber complete the harmonious overall picture. A special highlight of the Boker Sherman EDC is the protruding backspacer made of Damascus, which is equipped with a lanyard hole with an elongated, slotted design . The Damascus of the rear spacer was forged from various materials from M4 Sherman production by Chad Nichols in a Customized Ladder style, and resembles the tracks of a tank left in the ground by the heavy chains of the M4 Sherman.
