Abstract: An exemplary folding knife has a handle including an inner liner portion and an outer panel. The inner liner portion includes a locking member that is operable to move between an unlocked position and a locked position. The folding knife includes a blade having a tang portion pivotally connected to the handle. The blade is operable to pivot relative to the handle about a pivot axis extending through the tang portion between a closed position and an open position. The tang portion engages the locking member when the blade is in the open position and the locking member is in the locked position. The folding knife also includes a lever member pivotally mounted to the locking member. The lever member is operable to block the locking member from moving from the locked position to the unlocked position when the blade is open.

Abstract: A machine for cutting flat glass sheets has a fixed frame for supporting a worktable, which can be lifted, with rotation device, for loading and unloading sheets or sheet portions, and a movable bridge capable of performing a translational motion with respect to the worktable which supports a cutting head capable of moving on the bridge. The movable bridge slides on rails associated with a fixed frame and the rotation device for the liftable worktable has at least one lifting arm, which is fixed to the movable worktable and pivoted to the fixed frame, the lifting arm being contoured so as to extend around and not affect, during its rotation, the rails for the movable bridge, a portion of the rails extending so as to affect the region of rotation of the lifting arm.

Abstract: A feeding apparatus for a wide metal strip, wherein a plurality of through-holes are formed with predetermined gaps in a length direction and a width direction, into a cutter and pulls narrow metal strips formed by cutting the wide metal strip between the through-holes in the length direction so that through-holes are formed along only the length direction. The feeding apparatus includes a feeding-in apparatus that is provided on an entrance side of the cutter that feeds the wide metal strip into the cutter and a pulling-out apparatus that is provided on an exit side of the cutter that pulls out the narrow metal strips, which have been cut out by the cutter. A linking member drives the feeding-in apparatus and the pulling-out apparatus in concert so that the wide metal strip is fed into the cutter together with the narrow metal strips out being pulled out from the cutter.

Abstract: A power tool includes a motor, a foot plate, a biasing element, and an accessory. The motor is configured to move a saw blade in a repeating pattern of movement. The foot plate defines a saw blade opening. The foot plate has a first lateral wall and a second lateral wall that are spaced apart from each other so as to define a storage space. The biasing element is supported by the foot plate and has a detent. The accessory defines a detent recess configured to receive the detent therein. When the accessory is located in the storage space, so that the detent is received in the detent recess, the accessory is interposed between the anti-tilt structure and the foot plate.

Abstract: An out of front knife with an assisted opening mechanism has a handle, a blade mounted in the handle, a thumb stud that drives the blade, and an extending assembly that assists with extending the blade out of the handle. With two sliders and two springs of the extending assembly, only when the blade is intentionally pushed to move a preset distance and overcome a preset resistance, one of the springs pulls and assists the blade of the out of front knife to extend out of the handle. Therefore, the out of front knife with the assisted opening mechanism is used safely.
