Our take on the COAST DX340 Double Lock Folder

The COAST DX340 is a compact folding pocket knife with a 3.5-inch 7Cr17 stainless steel blade and a fiberglass-filled nylon handle. Its standout feature is the patented Double Lock, which backs up the liner lock to guard against accidental closure. At about 3.9 ounces and 4.8 inches closed, it carries easily for everyday chores and outdoor use. It sits in the budget-to-mid range of EDC folders, where its safety lock and three-position clip set it apart from plainer liner-lock rivals, though 7Cr17 steel holds an edge less well than the premium steels found on pricier knives.

About the COAST DX340 Double Lock Folder

The COAST DX340 is a compact folding knife for everyday carry. It has a 3.5-inch 7Cr17 stainless steel blade and a checkered, fiberglass-filled nylon handle that gives a secure, slip-resistant grip.

A patented Double Lock mechanism works with the liner lock to prevent accidental closure while cutting. Thumb studs on the blade allow one-handed opening with either hand. Notches on top of the blade add grip and control for detailed work.

The pocket clip has 3 positions, so the knife can be carried tip-up or tip-down on either side. It is meant for tasks such as camping, hiking, opening packages and light maintenance.

Questions and answers

What is the Double Lock on the DX340?
It is a patented secondary lock that works with the liner lock to keep the blade from folding while you cut. You release it along with the liner lock to close the knife.
How does the DX340 compare with a standard liner-lock folder?
The main difference is the added Double Lock safety system. Blade length, weight and the three-position clip are typical for a compact everyday folder.
Is the blade good for everyday tasks?
The 3.5-inch 7Cr17 stainless blade handles boxes, rope and camp chores. It holds an edge reasonably but needs more frequent sharpening than higher-grade steels.
Can I open it with one hand?
Yes. Thumb studs on the blade let you open it one-handed with either hand.
How does it carry in a pocket?
The three-position clip allows tip-up or tip-down carry on either side. At about 3.9 ounces and 4.8 inches closed, it sits comfortably in a pocket.
What is in the box?
The knife itself with its factory-fitted pocket clip. Check the listing for any extras included.
