Thanks so much for sharing your blade experiments! I never thought about lubricating with a crayon!
@NVSteamoji_2130420 - someone told me that paraffin (which is what crayons and candles are made of) attacks PLA but I haven't noticed any problem after years of using paraffin as a dry lubricant for PLA. It doesn't affect PETG either. I use it all the time when I print a bearing that has an axle rotating inside. Works pretty good in gear teeth too.
