Product Description

This AD20.5 pairs a stonewashed AUS-10A Shark Foot blade with black textured Grivory and Andrew Demko’s Shark-Lock™ on the spine.

Demko’s Shark Foot is a straight-edged blade shape, listed in the specs as a Wharncliffe style, with a 3.0" plain cutting edge on a 3.25" blade. A straight edge like this gives good control for push cuts such as opening boxes and breaking down packaging. The blade is AUS-10A, a high-carbon Japanese stainless steel valued for taking a fine edge and resisting corrosion; it is flat ground, stonewashed, and 0.13" thick. A ramp-like fin on the spine operates the Shark-Lock, and the thumb stud or thumb hole opens the blade. Black textured Grivory, a glass-fiber-reinforced nylon, covers steel liners for a 0.32" thick handle, with a tip-up clip set up for right- or left-hand carry. It closes to 4.25", weighs 3.5 oz, and is made in Taiwan.

Demko AD20.5 Shark Foot AUS-10A: Frequently Asked Questions

Answers about the stonewashed AUS-10A Shark Foot AD20.5 in black Grivory.

What is a Shark Foot blade?＋

Shark Foot is Demko's name for this blade shape. The spec sheet lists it as a Wharncliffe style, meaning a mostly straight cutting edge with a spine that drops toward the point. Many users like the shape for controlled push cuts.

What other versions are available?＋

Knifeworks also carries the AD20.5 in AUS-10A with a clip point blade in black Grivory (SKU DEMAD205F12), and with a stonewashed D2 Wharncliffe-style blade in black Grivory (SKU DEMAD205F25).

What is AUS-10A steel?＋

AUS-10A is a high-carbon Japanese stainless steel valued for taking a fine edge and resisting corrosion. No steel is completely rustproof, so wipe the blade clean and dry after use.

What grind and finish does the blade have?＋

The blade is flat ground with a stonewash finish. A flat grind tapers evenly toward the edge for slicing, and the stonewash helps hide light scratches from daily use.

What is the handle made from?＋

The handle is black textured Grivory, a glass-fiber-reinforced nylon (polyamide), over steel liners. It is 0.32" thick.

How does the Shark-Lock work?＋

Demko's Shark-Lock is located on the spine and is operated with a ramp-like fin. As with any folding knife, keep your fingers clear of the edge when closing it.

How big is it, and how does it open and carry?＋

It has a 3.25" blade with a 3.0" cutting edge, measures 4.25" closed, and weighs 3.5 oz. It opens by thumb stud or thumb hole, and the tip-up clip is set up for right- or left-hand carry. It is made in Taiwan and designed by Andrew Demko.

Who covers the warranty?＋

Demko Knives is the warrantor; Knifeworks does not warrant this product. Contact Demko directly for warranty terms and service.
