This is the "Bird and Trout-Ringed" blade. Single bevel ground for utmost strength and ease of maintaining the edge. 6-3/4in overall with a 2 1/4" blade with a full 1in handle hole so you can keep great control of the blade at all times! No more losing grip at the most inopportune moment! Weighing in at 1.6oz (Knife only), the BTR is perfect for any outing, light, strong and ready to work! Made from CPMD2 Steel Heat treated to 59-60rc, (this is NOT stainless, but almost! You will need to oil it to keep it from rusting, but it will take on a great patina as your use it!) . D2 takes a great working edge and is easily field maintainable. **The D2 blades feature our "Carbidized" carbide impregnated cutting edge, adding a "micro-serrated" cutting surface that has a rockwell hardness of 85rc, meaning more time in the cut and less time sharpening! Once you use a "Carbidized" blade you will ask your self how you ever went without one!** All of our blades are handmade: hand ground, hand finished and hand sharpened and include a black kydex flat sheath (Other colors available upon request and at additional charge!) and 550 paracord lashing material. These knives will come to you VERY SHARP! Use caution at all times!
