I took a close look at the new Glock model 78 field knife. It is a lot different than my first one (green in the photos). The first Glock knife is from the late 1980s the black Glock knife is new 2008 (approx) manufacture. From a few feet away they look the same but up close side by side there are many differences. the Glock field knife sheaths are also quite different. The Glock Knife blade is made of phosphate-treated Spring steel HRC55. The newer version of the Glock Field Knife weighs 7.27 ounces. The Glock Model 78 (no saw on blade) has a 6-1/2 inch blade and is 11-1/2 inches overall
What is not so obvious in the photos are the differences in polymer these are made from. The older Glock Field Knife is a smoother green material, the newer 2008 version is a softer material that seems to grip the skin and does not feel as slippery as the older material.
