Ever wonder what's wearing in your engine? I made this oil filter cutter to open up used filters for a quick inspection before they go in the trash. The bearings are from skateboard wheels and the blade is a replacement tubing cutter blade that can be found at any home center store.
Looks like you could also re-purpose your oil filter cutter into an institutional size can opener. It is a nicely finished tool. Thank you for all the photos.
