Some embodiments of the present disclosure provide a knife. The knife includes a handle and a blade, the handle includes a first casing and a second casing that are detachably connected, the blade is clamped between the first casing and the second casing, the blade is provided with a plurality of limiting openings that are arranged horizontally, a limiting structure corresponding to the limiting openings is arranged on the handle, and the limiting structure has a locking position and an unlocking position; when the limiting structure is in the locking position, the blade is fixed on the handle; and when the limiting structure is in the unlocking position, the blade can move forward or backward relative to the handle.

The present invention comprises a rectangular block, having a front face, a rear face, and two side faces. The front and rear faces have multiple pairs of aligned vertical slots, into which a knife can be inserted and moved up and down in a vertical cutting motion. The block is open at the top and openable at the bottom by means of a sliding or hinged trap door. In use, uncut chum is loaded into the block through the top opening, and the sliced chum accumulates within the block until the bottom door is opened, thereby depositing the sliced chum in a container beneath the block. The container serves to collect the chum and store it until it is used.

A device for macerating bait, making chum, or both is provided. The device has a main housing having a top openable end and a closed bottom openable end; a removable lid attachable to the top openable end, wherein the removable lid comprises at least a fluid flow hole configured to, when placed in a fluid and towed behind the vessel, port the fluid to flow through the housing through bottom openable end and through the top openable end; a push rod disposed through the removable lid; a concentric cutting member attached to the push rod at a lower end of the push rod, wherein the concentric cutting member comprises a series of blades that are intersecting and have cutting edges on a top and bottom of the blades. A method of macerating bait is also provided.

A cutting board and storage assembly being mountable in a boat for filleting fish on the boat includes a box that is mountable in a boat thereby facilitating the box to store objects for fishing. A knife sharpener is coupled to and is positioned within the box to sharpen a knife. A holder is coupled to the outer wall of the box to engage the blade of the knife for storing the knife. A lid is hingedly coupled to the box for closing the box and the lid has a top surface. The top surface defines a cutting board when the lid is closed and a fish, other object, can positioned on the cutting board for filleting or otherwise cutting.

This disclosure relates to a reciprocating saw blade for preparing fish. The reciprocating saw blade can comprise a blade and a wing. The blade can attach to a reciprocating blade. The blade can comprise a tip, a cutting edge, a spine, and a heel. The cutting edge can have continuous wavy serrations formed through a tooth from a plurality of teeth. The tip can form an inward curve towards the cutting edge. The cutting edge can be at one side of the blade while the spine can be at the opposite side. The spine can form an equidistant parallel line with the cutting edge. The heel can be at the rear end of the cutting edge. The wing can be at the rear end of the blade and can have an orifice and a prong. The orifice can be compatible to a quick-release mechanism of the reciprocating blade.
