14 cm Petty "125sc"

The geometry of this 14 cm petty knife resembles a laser. It offers excellent cutting power with a thin tip. Accordingly, some care is required when working with it.

The edge of this knife is made of the special alloy 125sc. This is an extremely pure unalloyed tool steel (carbon steel) with a high achievable hardness. The steel is easy to sharpen and is particularly suitable for thin blades with acute grinding angles.

The blade is differentially hardened and shows a clear hardness line (Hamon).

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. 

The handle is made of desert ironwood with a spacer made of moose antlers and a decorative rivet made of bronze. The tang runs through the entire handle and is riveted to the decorative rivet.
