With its sensible size and versatile shape, the Salt I knife is the saltwater counterpart of Spyderco's best selling Delica knife, but with several modifications. The Salt I has a more rounded tip that is a bit thicker at the point to better meet the types of cutting chores associated with boating and fishing. Its super sharp hollow ground blade with Spyderco's trademark Round Hole opens easily with just one hand - even with gloves. Plus, it features all of the rust-proof features of Spyderco's "Salt" family of knives.
The Salt I blade is made with state of the art H-1 steel - a precipitation-hardened steel with added nitrogen for markedly increased corrosion resistance. The H-1 alloy blade does something no other blade steel can, it remains 100% rust free and actually holds a sharp cutting edge.

Blade Shape Leaf Shaped Blade, developed by Spyderco, is similar to a spear point but is not quite symmetric, and is only sharpened on one side

Blade Grind full hollow grind blade shape with bevels that extend from the center of the blade down to the cutting edge. This grind maintains full blade thickness through a larger portion of the blade for increased strength. The bevels, however, are ground with a concave radius to create a finer edge profile which is very sharp (straight razors for shaving have this hollow grind), but at the cost of slightly less edge durability compared to flat sabre ground edges

Blade Edge the Salt I is offered in two versions:
A SpyderEdge edge grind, which is Spydercos two-step serration pattern of alternating large serrations and double small serrations - easily seen in the photos. Serrated blades hold their sharpness incredibly well because the actual cutting edge is hidden inside each mini-arch, protected by the pointy outer edge of the blade. The pattern increases the cutting edges surface area by up to 24%, and is especially useful on materials that are tough to cut with a plain edge - like ropes
The Salt I is also available with a traditional Plain, or Smooth, edge which cuts cleanly and sharpens quickly and easily.

Large trademark Spyderco Round Hole allows easy opening of the knife using the thumb of just one hand. In turn, the enlarged Round Hole creates a prominent hump in the top of the blade for your thumb to rest against while cutting.

Handle the Salt I has a high strength, lightweight, fiberglass reinforced nylon (FRN) polymer handle with Spyderco's tough and grippy "Volcano" waffle-textured pattern for enhanced grip. It comes in black or high visibility yellow.

A huge advantage all of Spyderco's "Salt" knives can be put away wet without rusting!
One of the highest quality blade steels available, the H-1 alloy in this blade holds an exceptional edge, and is 100% rust-proof
All internal metal components are specially treated to prevent corrosion and pitting
Rockwell hardness of 57-58rc makes for superior edge durability, so it lasts a long time between sharpenings
Reversible (for left or right hand use), non-rusting titanium, tip-up pocket clip secures the knife inside your back pocket; this knife carries best in a blade tip-up configuration for easiest access when needed
The clip's barrel screw is hollow, enabling a lanyard to be run through for retention when used around water, where once dropped, a knife is often irretrievable or lost
Back Lock style positive locking mechanism employs a rocker arm to engage a notch in the tang of the blade to lock it open; depress the recessed rear end of the rocker in the spine of the knife to unlock the blade; mechanism is recessed to prevent accidental unlocking
Closed length is 4"
