This is the Morakniv Basic 511 Fixed blade.
The Morakniv Craftline Basic 511 Utility Knife features a 3.6-inch fixed
blade made of high carbon steel that achieves high hardness, sharpens
easily and is exceptionally tough. High carbon steels are preferred in
applications that demand durability and frequent regrinding. The
material is harder than stainless steel, allowing it to hold a sharper
and more durable acute edge. An impact-resistant handle with a larger
shape fits comfortably in the hand. A finger guard on the handle
provides additional safety. Included with the knife is a hard plastic
Combi-Sheath, which provides a quick-connect feature for attaching a
second knife and sheath. Morakniv has been manufacturing the
highest-quality knives in Mora, Sweden since 1891. Mora Craftline Series
include sharp, durable, high-quality utility knives suitable for
construction, trade and industrial professionals.
