I started working on piston engine aircraft in the 1980s.
It is VERY common in aviation to cut open aircraft engine oil filters (for various reasons)
I started to do this with various vehicles, also - more than 30 years ago.
Since I never saw any "metal" in any oil filter (just little carbon chunks) - I decided to run one (a Motorcraft FL-1a) for 30,000 miles with 3x 10K oil changes.
I did actually spin it off, drain it, and look it well over before refilling it and reinstalling it each time.
After 30,000 miles, it was just fine... a little more carbon bits, but really it was just fine.
I have reused oil filters numerous times in my life - people that say "don't ever reinstall one" are speaking from simple ignorance, and nothing more.
