Tough. Dependable. Resilient. The Redi-Edge® Dog Tag Knife Sharpener is all of these things and more. We designed the sharpener to be portable, compact, and light weight so it can go with you wherever you go. While this sharpener is small and exactly the size of a dog tag, it still contains many features such as Duromite™ inserts, additional honing surfaces, and a ceramitized coating that will protect it in even the harshest of environments. Don’t be fooled by the dog-tag sized REDTL-40 and REDTL-60, they are full-featured, go-anywhere, high performance knife sharpeners. The Redi-Edge® Dog Tag features include military-grade aluminum construc-tion for extreme durability, long life and lightweight, a proprietary corrosion-resistant finish and a honing surface on the back. The Duromite™ inserts are harder than any knife blade; and factory pre-set to the inclu-sive angles of 40° and 60°. The 40° inclusive angle maintains a consistent 20° double cutting edge on most knives. The 60° inclusive angle maintains a consistent 30° double cutting edge on tactical knives. Sharpens, polishes & hones.
