Endura 4 Emerson Opener Trainer Knife -
Popularized and patented by Ernest Emerson of Emerson Knives, the opening feature is a hook curving out the blade's spine that catches the edge of your pant pocket when drawing the knife. It quickly opens the knife blade so it's locked and ready to use. The fact there is a learning curve in using the opening feature makes this trainer applicable.
Gaining proficiency in safely handling and opening an Emerson folder comes through repetitive practice. Delica and Endura Emerson Opener Trainers are identically sized, proportioned and weighted replicas of their "live" counterparts sans a sharpened edge and point. Designating them trainers are their red FRN handles. The handles have Bi Directional Texturing® for traction and screw together construction for cleaning and adjustment. To reduce weight the dual handle liners are skeletonized stainless steel and holes in the blade remove even more ounces. Phosphor bronze washers smooth open and close action and the clip attaches in four positions: tip up, tip down, and left or right hand.
Fiberglass Reinforced Nylon (FRN) -
A nylon polymer mixed with glass fiber that is then injected into a mold for making lightweight knife handles.
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.
Round Hole™ -
Round hole located in the knife blade used for one hand opening and closing of a 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.
