Current successful methods utilize contact destructive testing to develop a measurement protocol for sharpness however; it is in my opinion that testing in this manner, the instantaneous sharpness can never be known. Through-out this work, I investigate what physical properties determine sharpness, how failures occur in knives, the current state of art in knife sharpness testing, and then I seek to develop a new novel way of measuring knife sharpness through optical measurements.application/pdfenAll items in Research Commons are provided for private study and research purposes and are protected by copyright with all rights reserved unless otherwise indicated.KnifeSharpnessMeasurementOpticsDiffractionThesis2018-11-07
