Abstract: A foldable knife with multiple switching modes comprises a knife handle, a blade and a switch device. The knife handle has a resisting elastic plate, a positioning plate and a top cover. The resisting elastic plate has an elastic portion. The positioning plate is connected to the resisting elastic plate and has an elastic arm extended in the positioning plate. The top cover is mounted on the positioning plate and has a slide slot. The slide slot is formed on the top cover. The blade has a pressing rod and a manual pushing rod which are respectively formed on a surface of the blade towards the positioning plate. The switch device is mounted in the slide slot and has a pushing block mounted through the top cover, and the switch device is used to switch between an assisted opening mode and a manual opening mode.

Abstract: An out the front assisted knife has a casing, a blade and a secondary pusher. The casing has a secondary channel hole formed through the casing, extending axially, and disposed away from an axial inner end of the casing. The secondary pusher is axially movably mounted in the casing, protrudes out of the secondary channel hole of the casing, and axially abuts against the inner end of the blade. The secondary pusher is disposed away from the axial inner end of the casing, such that the user's hand holds at least half of the casing when pressing the thumb on the secondary pusher to extend the blade. Therefore, the user can hold the knife by the center of gravity of the knife, and thus can stably and conveniently operate the knife, thereby preventing the knife from dropping accidentally.

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.

Abstract: A writing pen, including a first pen portion containing an ink cartridge, a ferro rod extending from the first pen portion, and a removable second pen portion removably positionable over the first pen portion. The second pen portion includes a whistle integrally formed therewith. A third pen portion is removably positionable over the first pen portion and overlys the ferro rod to substantially conceal the ferro rod. A removable striker having a first end configured for contacting the ferro rod is installable onto the third pen portion so that either the first end of the striker or the second end of the striker extends outwardly from the third pen portion.

Abstract: A pocketknife has a handle, a blade, an assistant assembly and a locking assembly. The handle has a cavity defined in the handle. The blade is mounted pivotally at one end of the handle. The assistant assembly is mounted on the handle, assists to extend the blade out or retract the blade in the cavity and has a dial, a biasing lever and a spring. The dial is mounted rotatably in the handle and is connected securely on a proximal end of the blade. The biasing lever is mounted in the handle and is mounted eccentrically and pivotally on the dial. The spring is mounted around the biasing lever and biases the biasing lever to rotate the dial in two rotational directions to retract or extend the blade. The assistant assembly assists the user to open or close the pocketknife.

Abstract: A writing pen, including a writing pen portion; a ferro rod positionable to extend from the writing pen portion; and a striker portion positionable to extend from the writing pen portion to substantially conceal the ferro rod, The striker portion has one or more striker members which may be struck against the ferro rod for generating sparks.
