Abstract: A pattern knife assembly includes: a blade portion formed by forging and having a rear end integrally formed with a connecting sleeve, and a sheathing hole formed at a rear end of the connecting sleeve; and a tang portion formed by a casting or cutting process and having a tang hidden in a handle and integrally formed with a connector at the front end of the tang. The connector of the tang portion is inserted into the sheathing hole of the connecting sleeve of the blade portion and the connecting sleeve is welded to the connector, so that the connecting sleeve covers the connector and is exposed from the front end of the connecting sleeve to achieve the effects of combining the blade with the tang securely, providing a manufacturing process suitable for mass production, and showing the grain of the pattern steel in the exposed steel portion.

Abstract: A knife with laser engraved fishscale lines includes a knife body and a knife handle, and the knife body is a sheet member and has a cutting edge, a spine and two blade surfaces, and the blade surfaces are polished mirror surfaces, and the blade surface has the laser engraved fishscale lines which are indented lines indented into the blade surface, and the knife handle is combined with an end of the knife body, so that the knife has the effects of showing obvious laser engraved lines, lowering manufacturing cost, and preventing food sticking.

Abstract: A kitchen knife device designed to cut food includes a handle and a blade connected to an end of the handle. The blade has two opposite lateral surfaces, on each of which a plurality of recesses is formed and arranged side-by-side in a row. The recesses formed on the two lateral surfaces of the blade are symmetrical in position. Due to air existing in the recesses, food being cut with the kitchen knife device does not easily stick to the lateral surfaces of the blade, and a user needs not to take time to separate the split food from the lateral surfaces of the blade, making the cutting more efficiently.

Abstract: A knife includes a handle and a blade connected to an end of the handle. The blade is formed at one side for forming a cutting edge with a plurality of spaced connecting elements to define a space between any two adjacent connecting elements. A ceramic tip is firmly set in each space. Outer ends of the ceramic tips and the connecting elements are flush with one another and formed into the cutting edge of the blade. With the ceramic tips, the knife has a blade with increased wear strength and could be mass-produced at reduced cost.

Abstract: A knife assembly comprises a blade, a rear extension and a handle. The blade and the rear extension lie in planes that are perpendicular to each other, forming a cross at a connecting place. When the knife is used for cutting, the resulted counterforce spreads over a horizontal area so as to reduce the pressure and avoid injuries of the hand and the elbow.

Abstract: A knife blade assembly comprises a blade and a connecting piece. The connecting piece has an insertion part at an upper side. A rear extension of the blade is inserted in the insertion part and firmly connected therewith.
