Grandfather Blue Side Opening Automatic Knife Bayonet was made in taiwan and has a 440 stainless steel blade. This knife has a nice thick blade and a pocket clip on the back. When you push the button on the handle it snaps out quickly with a good hard snap. Very nice weight to the knife with a metal handle. The overall length of the knife is 8.5 inches with a blade length of 3.5 inches. These knives are no longer made and the best cheap knives you can buy. Once we run out, that will be the end of them!
