162 mm Petty "1.2562"

The geometry of this 162 mm petty knife falls somewhere between a userfriendly and a laser, featuring a very fine tip.

The cutting edge is made of 1.2562 steel. This specific material was produced by Lohmann using a vacuum melting process based on Armco 4 pure iron; the sheets were cross-rolled, ensuring the steel is of exceptionally high quality right from the source.

The cladding layers consist of a wild Damascus pattern made from 1.8974, 1.2235, 1.5634, and 1.2767 steels.

The handle is made from desert ironwood, featuring a spacer made of blue-stabilized maple and black fiber.

With the exception of stainless steels and PM steels, all the steels I use undergo an additional refining process. The flat material is cut into equal-sized pieces, precisely ground flat, and stacked into stacks at least 60 mm high. The stacks are then firewelded under air exclusion. This refined material forms the starting material for the subsequent blades. This process achieves a significantly finer and more homogeneous distribution of the alloying elements and, in combination with the correct heat treatment, small and evenly distributed carbides. Furthermore, microscopic gas inclusions and cavities from production are eliminated. This results in improved cutting edge stability and greater resistance to micro-chipping compared to the unrefined starting material, while maintaining the same hardness.

Of course, the blank was also forged with optimal temperature control and forming, and then subjected to extensive heat treatment (including deep freezing after hardening). This guarantees an optimally adjusted microstructure and finely distributed carbides.
