A knife is provided having both a multi-blade configuration for cutting multiple slices simultaneously as well as a single blade configuration for storage and single cuts. In some embodiments, the multiple blade configuration may be adjustable to define varying distances between the multiple blades.

A cooking knife includes: a handle, a plurality of blades and a sheath. The plurality of blades is disposed on the first portion and the second portion of the handle. The sheath includes two sheath shells and a pivot shaft, the two sheath shells being pivotally connected to each other by the pivot shaft in such a manner that the two sheath shells pivotally rotate by the pivot shaft in reverse direction to get close to each other or draw away from each other.

A cutting device for soft-cut foods, includes a base member and a cutter member. The base member has a top, a bottom and at least one side with a predetermined shape as defined from a top view footprint, and has a plurality of blade-receiving grooves on its top and positioned to receive a corresponding set of soft-cut blades of a cutter member. It also has handles and at least one alignment component for alignment of the cutter member so as to position the blades in alignment and above the grooves. The cutter member has a frame, a plurality of groove-corresponding blades, handles and at least one alignment component corresponding to the base member at least one alignment component.

Methods for reworking structures and reworked cellular core panels, reworked structures comprising the reworked cellular core panels, and guides and cutting apparatuses for reworking cellular acoustic panels and reworking cellular non-acoustic panels are disclosed.

The present invention is a new-type kitchen cutting tool suitable to be used in households, canteens, restaurants etc. It is an entirely-new multi-edge protective cutting tool consisting of several blade units and the supporting cutting tool holder for holding the blade unit, used for cutting the food material into slices, shreds and dices. The blade unit may be changed so that the food material may be cut into slices, shreds and dices with different sizes and thicknesses. The cutting tool edge, the thin thread functioning as the cutting tool edge and the chopping board may be protected through the combination of the protective plate and the elastic blade or the thin thread, greatly extending their service life. The present invention is featured as easy operation, convenient, safe, high efficiency, raw material-, energy- and time-saved, wide application range and good quality of processed products.

The present disclosure provides methods for biological sample preparation and analysis that use a chopping and fixing treatment in the preparation of dissociated fixed cells from biological tissue for use in either bulk assays, or in single-cell/single-nucleus assays, such as partition-based assays. The disclosure also provides assay methods, including partition-based methods, for use of the fixed cells prepared from biological tissue that can optionally be used in combination with un-fixing treatments. Kits comprising dissociation reagents, un-fixing agents, and other assay reagents for use in the methods are also provided.

A utility knife assembly includes a case having a slot in which two blades are received. A resilient plate is secured in the slot and includes two resilient fingers to push the blades out from the slot. A switch unit is connected to the case and selectively activates either one of the two blades to be pivoted out from the slot.

Living in the Northwest it is nearly impossible to own land and not wage war against invasive blackberries and brush. While attempting to fight this battle with a regular single blade trimmer attachment, it dawned on me that the real trouble is that a single cut only detaches the plant from its base, but leaves it suspended in neighboring brush. My invention with its multiple planes of bladelets turns the brush immediately to mulch for easy raking or to leave as mulch.
