Publication number: 20240316810Abstract: A razor blade is proposed. The razor blade may include a substrate having a cutting edge formed at a tip. A thickness T4 of the substrate measured at a distance of 4 ?m from the tip may be between 1.00 ?m and 1.70 ?m. A thickness T250 of the substrate measured at a distance of 250 ?m from the tip may be between 44 ?m and 60.56 ?m, for example between 47.5 ?m and 60.56 ?m. A ratio of the T4 to the T250 may be 0.032 or less. A rate of increase in thickness in a first section in a region distanced 40 ?m to 100 ?m from the tip may be less than a rate of increase in thickness in a second section in a region distanced 100 ?m or more from the tip.Type: ApplicationFiled: June 4, 2024Publication date: September 26, 2024Inventors: Hyun Ju LEE, Hyun Kyu JUNG, Seung Ki LEE, Kwang Choon RYU, Min Joo PARK

Publication number: 20240300126Abstract: A razor blade is proposed. The razor blade may include a substrate that has a substrate tip formed at an end portion and includes a first substrate facet and a second substrate facet extending from the substrate tip to both sides. The razor blade may also include a coating that is joined to the substrate and has a coating tip formed at an end portion and includes a first coating facet and a second coating facet extending from the coating tip to both sides and corresponding to the first substrate facet and the second substrate facet, respectively. The substrate may further include a third substrate facet extending from one end of the first substrate facet. A line tangential to the first substrate facet and a line tangential to the third substrate facet may not be parallel to each other.Type: ApplicationFiled: May 17, 2024Publication date: September 12, 2024Inventors: Min Joo PARK, Hyun Kyu JUNG, Seong Won JEONG, Myoung Jin KIM

Publication number: 20240246251Abstract: A razor blade is proposed. The razor blade may include a substrate including a substrate edge having a substrate tip formed at an end portion thereof. The razor blade may also include a coating layer disposed on the substrate and having a coating tip formed at the end portion thereof. The coating layer may include a pair of first facets extending from the coating tip and a pair of second facets extending from the pair of first facets. A gradient of the first facet may be smaller than that of the second facet based on a reference line passing through the substrate tip and the coating tip.Type: ApplicationFiled: April 5, 2024Publication date: July 25, 2024Inventors: Hyun Kyu JUNG, Min Joo PARK, Myoung Jin KIM, Seong Won JEONG
