From: Coating Cutting Blades with Thin-Film Metallic Glass to Enhance Sharpness

Typical load-displacement curves obtained from (a) bare, (b) Teflon-, and (c) Z-TFMG coated microtome blades upon cutting into pig muscles for 30 times. Red and blue curves respectively represent the first and the last cuttings, while green indicates the cutting having the highest load.
