Douk-Douk Black Folder Knife 815
Description
The Douk-Douk 815 is a French pocket knife with a 3.13" carbon steel blade, a black folded steel handle, and a bail for a lanyard. The Cognet family has made it in Thiers, France, since 1929, using the same simple construction: a blade, a folded sheet-steel handle, a backspring, two rivets, and a bail. The blade carries the Douk-Douk etching, and the knife is 4.38" closed.

From Thiers to the Far Corners of the French Empire
Thiers has been the capital of French knifemaking for centuries, and the Cognet cutlery firm has worked there since 1835. In 1929, the Cognet family designed the Douk-Douk as an inexpensive working knife for France's colonies in the South Pacific. They named it after the Duk-Duk, a Melanesian spirit figure whose masked costume appears on the handle. The knife spread far beyond Oceania into French Africa and around the world, carried by laborers, sailors, soldiers, and explorers who needed a knife that was cheap, tough, and easy to sharpen. Cognet remains family-owned and is the only maker of the authentic Douk-Douk.
Six Parts and Nothing Extra
The blade is high carbon steel, hardened to about 50 to 53 HRC and hollow ground on water-cooled wheels. That relatively soft temper makes it very easy to sharpen, even on a rough stone or the bottom of a coffee mug. The curved, scimitar-like clip blade gives you plenty of belly for slicing. The handle is a single sheet of steel folded into a channel and given a ferro-blackened finish, a bluing process similar to the one used on gun barrels. The knife is a slip joint, so the backspring holds the blade open and closed but doesn't lock it.
The Fisherman's and Traveler's Knife
Cognet's own team calls the Douk-Douk ideal for fishermen and adventurers, and that's how most owners use it: cutting line and rope, cleaning fish, slicing fruit and bread, and whittling at camp. It's thin enough to vanish in a pocket and light enough to hang from a lanyard or keyring by the bail. Because the blade is carbon steel, it will darken with use. Wipe it dry and add a drop of oil now and then, especially after cutting food or working near salt water.

Curious About Sizing?
Given the massive variety of clothing we carry, a standard sizing guide is incredibly helpful for customers seeking the best fit.
Please understand that surplus varies widely in fit and cut and this sizing chart is general advice rather than tailor-level fitting.
Nearly every military has different sizing charts and schemes, which is why we've taken the time to put together this brief tutorial.
Jacket & Shirt Sizing
In absence of an established military size chart, we measure each jacket or shirt from armpit to armpit to get a rough idea of how it fits. If a garment is between sizes, we mark it one size down. For example, if a shirt measures 19.75" from pit to pit, it is marked as a small rather than medium.
To measure pit to pit, close up your shirt or jacket and measure from armpit to armpit.
This is our measurement guide that we use to measure garments without an existing military size chart:
14"-15" PtP = XXS
16-17" PtP = Extra Small
18"-19" PtP = Small
20-21" PtP = Medium
22-23" PtP = Large
24-25" PtP = Extra Large
26-27" PtP = XXL
28-29" PtP = 3XL
Pant Sizing
We typically convert pants to US waist and inseam sizes. If a pair of pants is between sizes, we mark it one size down. For example, if a pair of pants measures as a 33 waist, it is marked as a 32 waist.
To take these measurements we lay a pair of pants flat on the ground. We then measure across the waist and double the measurement. For example, if a pair of pants measures 16" across the waist it will fit a US 32 waist.
To determine inseam we measure from the crotch seam to the bottom of the cuff. For example, it a pair of pants measures 30" from the crotch seam to the bottom of the cuff we will list it as a 30 inseam or 30L.
