This might be a redundant question & in the wrong part of the forum, if so I apologize. Can anyone point me toward a tool that is used to cut open oil filters to inspect performance and it's contents?

Thank you,.....Kent
 
I like my Longacre. Lots of different cutters found on the internet. Most of them will do the job. The ones sold for aircraft use are pricey and overpriced for the average joe.

I always wonder about this, an average joe shmo like me even if they open a filter, what can they understand form it? Besides looking at structural integrity and as such?

I've been using the Harbor Freight pipe cutter for a few years now. Oil filter in the bench vise. Has other applications.

$16

I used a bench vice and just cut around the edge with aviation shears. Not the easiest method but only takes a minute or two.
 
Angle grinder with a cutting wheel. 30 seconds later (including time to turn it a few times on the vice) and it's open.

Yup, and a dremel with a cutoff wheel works too, as does a hack saw, but they all leave metal flakes behind.
The filter openers with the cutting wheels do not leave any debris behind.

I wish Harbor Freight still had the No.3 exhaust cutter, I read that it worked great for most all filter sizes and was cheap.

I tried one of those, it worked OK, but crushed the can some and was not the best cut.

Also, most will not fit around larger filters. I have seen a 6" chain one on e-bay that would probably fit larger filters.
This is what the 4" chain did to the filter from my F150:
