Serrated Blunt Tipped Blade Assist I Folding Knife -
Spyderco named this knife after its principal job function, to assist. The Assist was designed for emergency, fire, and rescue professionals (and for the well equipped civilian) who rely on their knives to function flawlessly under pressure. Even with twenty five years experience in making rescue knives, Spyderco is still offering new high tech features and the Assist model showcases the latest and greatest in this knife genre.
The VG-10 patented blunt tipped blade is a toothy eighty percent SpyderEdged for aggressively cutting seatbelts and fibrous material. The last inch of the tip we've left PlainEdge for detailed cutting (think sharpening pencils). Perched above the Round Hole, a Cobra Hood positions the thumb directly over the hole for quick blade deployment, then doubles as a leveraging platform for the thumb. The wavy pattern cut from the top of the blade (created by a fireman from Sweden) and along the inside of the handle let you place a piece of rope (between the half open blade and handle) and scissor the blade shut. Especially convenient for cutting rope in and around flesh without having to fully open and expose the knife's blade. The FRN handle is a molded wonder of Bi Directional textured contours and bulges that ergonomically wrap around your palm. In the closed position, squeeze the blade deeper into the handle and a retractable carbide tip protrudes out from the base for breaking glass. Outlined in safety orange on the handle's spine is a shrill and attention pitched survival whistle. Carries left and right handed, tip up by means of a tension wire clip.
Serrated Blade -
A serrated blade has a cutting edge that has many small points of contact with the material being cut. By having less contact area than a smooth blade, the applied force at each point of contact is relatively greater and the points of contact are at a sharper angle to the material being cut.
VG-10 Stainless Steel -
VG-10 has Carbon (C) content between 0.95-1.05, Chromium (Cr) content between 13.0-15.0, Molybdenum (Mo) content between 0.2-0.4, and contains less than 0.25 of Nickel (Ni). During forging, Mo and Cr forms hard double carbide bonds which help improve the abrasion and corrosion resistance of the steel. It has a hardness of 58-61.
Spyderco's two step serration pattern of one large and two small serrations. This pattern increases the cutting edge by 24%.
This is a sharpened knife blade with no serrations or teeth. It is sometimes called a smooth blade.
Fiberglass Reinforced Nylon (FRN) -
A nylon polymer mixed with glass fiber that is then injected into a mold for making lightweight knife handles.
Round Hole™ -
Round hole located in the knife blade used for one hand opening and closing of a knife blade.
Cobra Hood™ -
A machined flange of steel positioned over the Spyderco round opening hole on the spine of the blade which directs and positions your thumb over the hole for quickly opening the knife blade.
Bi Directional Texturing -
A texture molded into an FRN handle, which is a series of graduating, sized forward and backward steps that radiate outward from the center of the handle. This texture provides resistance to slipping and sliding when gripped in the hand.
Tip Up and Tip Down -
Refers to which direction the folded knife if positioned by its pocket clip. When closed and clipped in a pocket, whichever direction (up or down) the blade's tip sits defines if it is termed tip up or tip down.
Using both hands with equal ease. Pertaining to knives, it is a knife that is not solely designed for a left or right handed person but can be used with equal ease by both hands.
