Abstract: A diamond-containing blade includes a blade body having at proximal end a connection part to be fitted into a gripper; and an edge longitudinally formed along one side of the blade body, wherein the blade is manufactured by a process in which a powder mixture for constituting the edge, including 20 wt % or less of diamond particles coated with Ti and having a particle size of 20 ?m or less and residual Ti powder or Ti alloy powder, is charged in a space of a mold corresponding to the edge, Ti powder or Ti alloy powder for constituting the blade body is charged in another space of the mold corresponding to the blade body, the charged powders are pressed to obtain a molded product, the molded product is sintered to obtain a sintered body, and then an edge of the sintered body is sharpened.

Abstract: Disclosed herein is a diamond-containing blade, including: a blade body having at proximal end a connection part to be fitted into a gripper; and an edge longitudinally formed along one side of the blade body, wherein the blade is manufactured by a process in which a power mixture for constituting the edge, including 20 wt % or less of diamond particles coated with Ti and having a particle size of 20 ?m or less and residual Ti powder or Ti alloy powder, is charged in a space of a mold corresponding to the edge, Ti powder or Ti alloy powder for constituting the blade body is charged in another space of the mold corresponding to the blade body, the charged powders are pressed to obtain a molded product, the molded product is sintered to obtain a sintered body, and then an edge of the sintered body is sharpened.

Abstract: The present invention relates to a blade that comprises a blade main body and an edge part. In the blade main body and the edge part, one or more comprising the edge part are manufactured by using a powder composition that comprises less than 5% by weight of the ultra-hard particle powder having a particle size in the range of 1 ?m to 5 ?m based on a total weight of the powder composition and the balance metal powder forming a matrix according to a powder metallurgy process. The blade according to the present invention has a sawlike or wavy edge part to provide an excellent cutting ability. Even though the abrasion occurs by using the blade, since the sawlike or wavy edge part is semipermanently maintained, the cutting ability is not reduced.

Abstract: In a cutter that is used for bale packaging in the distribution industry, a cutter blade where a plurality of cutting lines are carved. If the cutting edge of the cutter blade becomes dull, the end of the cutter blade is broken off at the cutting line. The broken portion of the blade is considered a dangerous waste. However, solution to avoid the dangerous has not been considered.

Abstract: The present invention provides a diamond containing edge material and a manufacturing method thereof in that the diamond containing edge material includes diamond particles thinly coated with a metallic thin film compared to the conventional Nickel (Ni) coating, and thus, the present invention provides an edge material including a plurality of diamond particles having 100 ?m or less diameter at least partially coated with Titanium; and a matrix material retaining said diamond particles after processing and containing at least 50 weight percent of Titanium in relation to the total weight of said edge material.
