The DX340 from Coast knives is designed for safety and convenience. It features a patented Double-Lock safety switch mechanism which works in conjunction with the primary liner lock to prevent dis­engagement when the knife is open, even if the liner lock is inadvertently disengaged. A black coated aluminum handle adds incredible strength and durability. Thumb studs on both sides of the blade make opening it easy either right or left handed. This is a hard-working tool at an affordable price, and it's backed by Coast's lifetime warranty against defects in materials or workmanship.

Phenomenal knife!
Jameson F.
I bought one of these at a Home Depot, because my old work knife broke and I needed a cheap replacement before I could get a better one. I haven't gotten another knife since! The blade holds up very well, the edge is easy to hone and stays very sharp. The entire thing is very sturdy, I've never had a single wobble of any sort, and I use this thing every day. I highly recommend it, its a suburb work knife that wont let you down!
