| 20100192381 | FOLDING KNIFE WITH BLADE OPEN ASSISTING FUNCTION - A folding knife includes a handle and a blade pivotally supported on the handle. A tang of the blade includes a cam surface. The cam surface has a substantially arcuate guiding portion and an engagement portion that is formed continuously from one end of the guiding portion. The handle has a blade locking mechanism. The locking mechanism includes a slider and a coil spring that biases the slider. The slider is movable along the longitudinal direction of the handle between a lock position, at which the slider is engaged with the engagement portion, and an unlock position, at which the slider is separate from the engagement portion. The slider has a pressing portion that is engaged with the blade when the blade is arranged at the folded position. By moving the slider in the direction from the lock position toward the unlock position when the blade is at the folded position, the pressing portion presses the blade out of the folded position toward the open position. | 08-05-2010 |
