1970 - Burst from Kershaw, Black Polyimide Handle, Plain Edge Blade
The aggressive, spiked look of the new Burst is sure to draw the eye and plenty of positive comment. You’ll appreciate its SpeedSafe® assisted opening, which is easily accessed with a convenient flipper. Oh yes; and do notice that flipper. Kershaw directed the blade grind all the way down the flipper for a sweeping line. The handle is injection-molded, glass-filled nylon; a stout locking liner secures the blade during use. The Burst also includes a reversible pocketclip.
SpeedSafe® is the patented, assisted opening mechanism pioneered by Kershaw that makes it fast and easy to open a knife one-handed. SpeedSafe also makes it possible for Kershaw to ensure that even a large blade can move out of the handle just as smoothly and easily as a smaller one. Plus, many of their assisted folders are ambidextrous—and open with a flipper or a thumbstud on both sides of the blade—so they’re just as easy to use left-handed or right. To open a SpeedSafe knife, the user must apply manual pressure to overcome the resistance of the torsion bar. This means that SpeedSafe knives do not meet the definition of a switchblade; they do not deploy with the push of a button or by gravity alone. Once open, the blade locks safely into position until the user releases it.
