This is a (quite literally) really sharp example of a brass handled Model 1918 Trench knife. It was manufactured by Landers, Frary, and Clark Co. of New Britain Connecticut aka LF&C. LF&C manufactured a wide variety of household products from 1862 until the company was bought by General Electric in 1965. For over a century, the Company manufactured a variety of products from Coffee Percolators and Grinders to roller skates and mouse traps. During World War One, LF&C turned turned away from commercial production to military products. The US Models 1917 and 1918 trench knives were only a couple of the many products LF&C Co. manufactured for the American Expeditionary Forces that were headed to France.
This knife is in excellent condition overall still retaining about 80% of its original blackened finish over the brass handle and steel blade. The handguard is perfectly straight with no bends or repairs. The iron skull-crusher retaining nut at the back of the handle is intact and has never been ground down. The double blade is in beautiful shape and has never been sharpened or altered with the exception of a couple tiny nicks along the edge of the upper blade. A beautiful example of a scarce American fighting knife. No scabbard.
