A method of operating a computer-controlled industrial robotic arm to sharpen a knife can include performing a profilometer scan of the knife and determining the scan is incomplete or missing data. Rather than re-scanning the knife, a template having a similar geometry to completed sections of the scan can be selected from a library of template knife profiles. The templates in the library can be generated from previously completed scans of other knives. A completed proxy knife geometry can be created by substituting the template geometry for missing scan regions or in place of the incomplete scan. The completed proxy knife geometry can then be used for controlling a robotic arm to perform a sharpening operation upon the knife.
