Product Description

A black-finished AUS-10A Shark Foot blade against bright orange textured Grivory gives this AD20.5 a bold two-tone look, with Andrew Demko’s Shark-Lock™ on the spine.

The 3.25" Shark Foot blade carries a straight 3.0" plain edge for controlled push cuts on boxes, tape, and cord. It is AUS-10A, a high-carbon Japanese stainless steel valued for taking a fine edge and resisting corrosion, flat ground, 0.13" thick, and finished in black. A ramp-like fin on the spine works the Shark-Lock, and the thumb stud or thumb hole opens the blade. Orange textured Grivory, a glass-fiber-reinforced nylon, covers steel liners for a 0.32" thick handle, and the tip-up clip is set up for right- or left-hand carry. It is 4.25" closed, weighs 3.5 oz, and is made in Taiwan.

Blade: 3.25" AUS-10A Shark Foot, black finish, flat grind, 3.0" plain edge, 0.13" thick
Lock and opening: Spine-mounted Shark-Lock fin, thumb stud and thumb hole
Handle: Orange textured Grivory over steel liners, 0.32" thick

Demko AD20.5 Black Shark Foot Orange Grivory: Frequently Asked Questions

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

How is this different from DEMAD205F23?＋

This version has a black-finished AUS-10A blade. DEMAD205F23 is the same orange Grivory Shark Foot with a stonewashed blade.

Is there a D2 version with a black blade and orange handle?＋

Yes. Knifeworks also carries orange Grivory AD20.5s with a black-finished D2 Wharncliffe-style blade (SKU DEMAD205F26B) and with a black D2 clip point (SKU DEMAD205F16B).

Will the black finish wear?＋

Like most black blade finishes, it can show wear with heavy use. If you prefer a bare-steel finish, the stonewashed version (SKU DEMAD205F23) is an option.

What is a Shark Foot blade?＋

Shark Foot is Demko's name for this shape: a straight cutting edge with a spine that drops down to the tip. Many users like it for controlled push cuts such as opening boxes and trimming cord.

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 is the handle made from?＋

The handle is orange textured Grivory, a glass-fiber-reinforced nylon (polyamide), over steel liners. It is 0.32" thick, and the bright color stands out in a pack or toolbox.

How does it open, lock, and carry?＋

It opens by thumb stud or thumb hole, and Demko's Shark-Lock on the spine is operated with a ramp-like fin; keep your fingers clear of the edge when closing it. The tip-up clip is set up for right- or left-hand carry. It has a 3.25" blade, closes to 4.25", weighs 3.5 oz, and is made in Taiwan to Andrew Demko's design.

Who covers the warranty?＋

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