“…When using a knife under real-world conditions, various tests must be performed because the cutting method changes depending on how the user uses the knife and the object to be cut 5,6 . In particular, the differences between Su et al 7 and McGorry et al 8,9 evaluation methods suggest that the test method to determine the performance requirements can differ depending on how the blade is used. However, the common requirements for all blades include sharpness and durability.…”

Blades that are mass-produced and distributed as industrial products are indispensable tools in our lives. Some of these inexpensive and convenient blades are considered disposable. However, by improving their performance with a small amount of additional machining, we could reduce waste and improve society. We performed underwater laser machining using a 5-ns pulsed laser to improve the abrasion resistance. By using a mass-produced cutter blade, the cutting edge was laser peened, and a sharpness test was conducted with a sharpness tester. The measured values showed that the abrasion resistance could be approximately doubled. Additionally, in this work, sharpness tester measurements were found to be applicable for evaluating the performance of laser peening effects.

Steels for sharp edges or tools typically have martensitic microstructures, high carbide contents, and various coatings to exhibit high hardness and wear resistance. Yet they become practically unusable upon cutting much softer materials such as human hair, cheese, or potatoes. Despite this being an everyday observation, the underlying physical micromechanisms are poorly understood because of the structural complexity of the interacting materials and the complex boundary conditions of their co-deformation. To unravel this complexity, we carried out interrupted tests and in situ electron microscopy cutting experiments with two micromechanical testing setups. We investigated the findings analytically and numerically, revealing that the spatial variation of lath martensite structure plays the key role leading to a mixed-mode II-III cracking phenomenon before appreciable wear.
