The present invention discloses a folding knife, which belongs to the field of manual cutting tools. Conventional folding knives suffer from the drawbacks of cumbersome operation of the locking mechanism for preventing accidental folding, and potential safety hazards as fingers are located in the folding path of the blade during folding. In the present invention, a finger control part protrudes from a side surface of a front end of a handle part for a finger to apply an unlocking force rearward. The handle part is provided with a forward force application contour feature. A distance between the finger control part and the forward force application contour feature is adapted to allow that fingers of a single hand are able to manipulate the finger control part as the same hand grips and controls the forward force application contour feature, and the hand applies a forward control force to the forward force application contour feature as the fingers apply the unlocking force rearward to the finger control part. Therefore, by gripping the forward force application contour feature with one hand and using a finger of the same hand to apply the unlocking force rearward to the finger control part, the hand is caused to apply the forward control force to the forward force application contour feature. The opposing directions of the unlocking force and the control force cause the handle part to be squeezed and controlled in the hand, thereby allowing the fingers to avoid the folding path and then perform the operation of folding or unfolding the folding part.
A folding knife, comprising a handle part and a folding part pivotally coupled to the handle part via a pivot so as to be folded toward the handle part and unfolded from the handle part, a rear end of the folding part and a front end of the handle part being provided with a locking mechanism for locking the folding part relative to the handle part, wherein the locking mechanism comprises a finger control part for unlocking the locking mechanism, the finger control part protrudes from a side surface of the front end of the handle part for a finger to apply an unlocking force (F1) rearward, the handle part is provided with a forward force application contour feature, and a distance (L) between the finger control part and the forward force application contour feature is adapted to allow that fingers of a single hand are able to manipulate the finger control part as the same hand grips and controls the forward force application contour feature, and the hand applies a forward control force (F2) to the forward force application contour feature when the fingers apply the unlocking force (F1) rearward to the finger control part.
