Abstract: A knife allowing rapid and safe replacement and securement of a blade which can be fixed to a front end of a connecting base of the knife. The connecting base has a rear end that can be connected to a handle, and includes an upper base body, a lower base body, a lock-release member, and a spacer plate that can be located between the upper and lower base bodies and form an engaged-connection groove along with the base bodies therebetween. The engaged-connection groove matches, and enables the insertion therein and engagement therewith, a portion of the blade at or adjacent to the rear end thereof. The lock-release member can be arranged on the connecting base for a user to set the blade into a locked state, in which the blade is securely positioned and cannot be detached, or an unlocked state, in which the blade can be detached.

Abstract: The present invention is to provide a demolition utility tool which includes a bar-shaped handle provided with a first tool portion and a second tool portion at two ends thereof, respectively. The first tool portion is formed with a gas shut-off feature for rotating and thereby turning off a gas valve switch, and has one side provided with an axe blade for chopping or breaking apart an object and another side provided with a pike for cutting into an object by a striking action. The second tool portion is U-shaped and configured to rotate a toothed locking element with ease while holding the handle. Therefore, instead of carrying a good number of demolition tools around, a firefighter only needs to bring the demolition utility tool for performing all kinds of demolition operations while in firefighting.

Abstract: The present invention is to provide a folding knife, which includes a handle provided therein with first and second slots, wherein the first slot extends slantingly from a first end toward a second end of the handle; a pushing element formed with a third slot slantingly extending in a direction opposite to the first slot and at least one post; and a pressing element having one end pivotally provided in the handle and another end provided with at least one sliding block capable of moving in the first and third slots and an abutting portion capable of abutting against the blade. When the pushing element is pushed, the post moves along the second slot and drives the sliding block to move along the first and third slots, thereby enabling the abutting portion to apply force to the blade and rotate the blade out of the handle to a predetermined angle.

Abstract: The present invention is to provide an assisted folding knife, which includes a handle; a blade having a first end pivotally connected to a first end of the handle; a first resilient element having a first end positioned proximate to a second end of the handle and a second end extending to the pivotally connecting position of the handle and blade, such that when the blade has been rotated out from the handle by a predetermined angle, the first resilient element produces a torque tending to rotate the blade out of the handle; a post fixed on the blade, and exposed outside the handle when the blade is completely received in the handle; and a poking element pivotally provided in the handle and having a first end lying outside rotation of the blade, and a second end pressed against the post when the blade is completely received in the handle.

Abstract: A folding knife includes a handle, a blade, a resilient element and a poking element. The blade can be turned into or out from the handle. The resilient element has an end fixed to the handle and another end extended to a position of connecting the handle and the blade. If the blade is stored in the handle, the resilient element produces a torque to turn the blade into the handle. When a force is applied to turn the blade out from the handle, the resilient element produces a torque to pop the blade out from the handle automatically. The poking element is provided for turning the blade. When the blade is in the handle, the poking element presses against the blade, such that if a user pokes an end of the poking element, another end of the poking element turns the blade out from the handle.

Abstract: A foldable knife comprises a blade having an end pivotally connected to an end of a handle, and a spring having two ends connected to the handle and blade respectively, so that the spring can apply a torque to the blade to rotate the blade out of the handle. A blocking element is provided at an inner portion of the handle. A switch element pivotally connected to the inner portion of the handle has a first end extended out of the handle. When the blade is completely received in the handle, a second end of the switch element bears against the blade. When the user pushes the first end of the switch element, a positioning portion formed on the blocking element is disengaged from an engaging portion formed on the blade, so that the torque of the spring drives the blade to spring out of the handle.

Abstract: A folding knife comprises a blade and a handle, wherein the handle is formed by bending a metal sheet into a shape of inverted U-section for clamping an item (e.g., a lighter) therein and comprises a latch formed by punching on one side thereof adjacent to the receiving space in a direction opposite to the receiving space. The blade has one end pivotably secured to one end of the other side of the handle having the latch and the one end of the blade is lockingly fastened by the latch when the blade is in its opened position. The blade is unfastened when a predetermined pressing force is exerted on the latch toward the receiving space such that the blade may pivotably retract onto the other side of the handle. Thus, the folding knife can be mounted with the item (e.g., the lighter) for the functions of cutting and lighting.

Abstract: A folding knife has a handle and a blade. The blade is pivotally coupled to the handle. The handle includes a latch element, a resilient element and a turning element. An end of the resilient element is fixed into the handle. The latch element is pivotally coupled into the handle. An end of the latch element is extended to an end of the blade. Another end of the latch element presses against another end of the resilient element. The resilient element pushes the latch element to turn the blade out from the handle or store the blade completely into the handle. The turning element is pivotally coupled into the handle, such that when a force is exerted to push the latch element towards the resilient element to release the blade, the blade can be movably turned out from the handle or stored into the handle.

Abstract: The present invention discloses a folding knife, which includes a knife handle having a slot; a blade pivotally coupled to the knife handle and turnable into or out from the knife handle; a resilient device fixed to the knife handle and extended to a position proximate to the pivotal connecting position, such that when the blade is stored completely into the knife handle, the resilient device produces a torque to turn the blade into the knife handle, and when the blade is turned to a predetermined angle out of the knife handle, the resilient device produces a torque to turn the blade out from the knife handle; and a turning device, pivotally coupled to the knife handle and having a protruding pillar passed through the slot for securing or releasing the blade as required.
