Spyderco Delica 4 with Emerson Opener incorporates into its famous Delica folding knife the popular and patented blade opening feature of Ernest Emerson.  The Emerson opening feature is a hook curving out the top of the knife's blade. When pulling the knife out from a pocket, the Emerson opener catches the pocket's edge and quickly opens the knife blade for ready use.  The knife can also be taken out of the pocket without using the opening feature.  You can do this by simply pulling the knife straight up and out, with your fingers holding the top of the closed blade.

This little knife’s very sharp and rust resistant VG-10 blade is made up of stainless steel with a round hole design and a rugged screw-together construction and phosphor bronze washers. The handle is made up of Fiberglass Reinforced Nylon (FRN) that provides a good grip. Both the liner lock and top of the blade have "jimping", which are ridges cut into the metal for your thumb to grip onto and which also helps in handling and closing the knife. The pocket clip holds well and can be adjusted to four different positions to suit your carry preference. 

Spyderco Delica 4 folding knife’s design and construction is very solid but lightweight and can be easily clean and oil. This knife has also a lanyard hole for the attachment of a lanyard or a lace. A very good and high quality knife for a reasonable price.
