Built by GEC and Bark River. Blade is convex ground 1095 carbon steel. They have stainless liners and nickel silver bolster, sheild and pins. Super high quality knives built by two of the best knifemaking companies in the world. Fit and finish is perfect. All handle materials are gorgeous and the highest quality. These knives come with a super high quality custom vegetable tanned leather pocket sheath that is stamped "SCAGEL." One of the finest quality knives that you can buy today in my opinion! William Scagel would be very happy that his name is on these knives!
