Tough. Dependable. Resilient. The Redi-Edge® Small Dog Tag Knife Sharpener is the most portable, compact, and light weight knife sharpener in the Redi-Edge® lineup. Although small, this sharpener still contains many features such as Duromite™ inserts and a ceramitized coating that will protect it in the harshest of environments. (Comes with a lanyard hole for easy attachment to rope, clips, or a chain.)Don’t be fooled by the smaller than dog-tag sized REDTS-40 and REDTS-60, they are full-featured, go-anywhere, high performance knife sharpeners. The Redi-Edge® Small Dog Tag features include military-grade aluminum construction for extreme durability, long life and lightweight, a proprietary corrosion-resis-tant finish and a honing surface on the back. The Duromite™ inserts are harder than any knife blade; and factory pre-set to the inclusive 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.
