Warthog’s Xtreme Edge VSharp knife sharpener maintains a constant angle while sharpening both edges of the blade simultaneously.

With adjustable spring tensioning, the sharpening angle is adjustable between 20 and 30 degrees.

Featuring replaceable slide-on diamond hones in a variety of grit grades, the VSharp has a durable, high-impact ABS frame and rust resistant components, making it ideal for fishing.

Supplied in a handy PVC carry case (with belt mounting) and offered with a one-year warranty, this South African-made product promises consistently sharp knife edges with minimal blade erosion.

Available from select outdoor and sports retailers and online.

Includes a tutorial on DVD.
