Kentucky’s Eagle edge pocketknife 2.75-inch Abalone handle with 3 stainless-420-C blades

Description

Eagle edge knife is a Kentucky Cutlery company is known for its high-quality pocketknives, 3 blade stainless steel 440-C blue bone Eagle Edge Pocket Knife.

The 420-C-Eagle Edge Abalone pocketknife is a popular choice known for its 420HC stainless steel, which offers durability, corrosion resistance, and ease of sharpening. This knife is designed for everyday carry and is available in various styles, including single blade and multi-blade options. The 420HC steel is a low-cost option that provides good performance for cutting tasks, making it suitable for both casual and practical use.                                     

Alloy 420 is a hardenable, martensitic stainless steel that is a modification of Alloy 410. Similar to 410, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Alloy 420 has higher carbon content than Alloy 410 which is designed to optimize strength and hardness characteristics. It has good ductility it the annealed condition but is capable of being hardened to a minimum Rockwell hardness of 50 HRC, the highest hardness of the 12% chromium grades. Due to its hardening properties, Alloy 420 is not often welded, although it is possible. Martensitic stainless steels are designed for high hardness and sometimes other properties are to some degree compromised. Corrosion resistance is lower than the common austenitic grades and their useful operating range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished.

Specifications: UNS S4200

Alloy 420 is used for a variety of applications where good corrosion and outstanding hardness is necessary. It is not usually used at temperatures exceeding 800^oF (427^oC) due to quick hardening and loss of corrosion resistance. Examples of applications that use alloy 420 include: _Block sharpeners use D-2 steels sharpens 420-C steel great.
