The only knife and broadhead sharpener you will ever need. All of our hunting and fishing buddies have said the same thing - they have never used such an easy and effective sharpener, EVER! The Redi-Edge knife sharpener works so well because of the hardness of the blades. To sharpen a knife your blades must be harder than the knife you are trying to sharpen. The duromite steel blades are harder than any other cutlery steel on the market today. Use your new Redi-Edge to sharpen any knife in the field, on the water, and in the kitchen. Great on broadheads and fish hooks too.This knife sharpener will last a lifetime and even has a lifetime warranty. After many years and many sharpenings you can flip the blades, then after many more years and many more sharpenings you can order replacement blades (now only $10. for a set of two). duromite cutter blades are factory set at a 40 degree inclusive angle maintaining a consistent 20 degree double edge on your blades. Compact 5" size fits in your pocket. Sheath included. Available in green or black, right or left-handed. Made in the USA.
