Who makes a decent oil filter cutting tool for a decent price? I've always wanted to cut open my oil filters in a clean manner (with the right tool) for inspection.

I found a decent one on Summit ... thanks. On sale for $35.

I thought of doing it that way, but seems like it would be messy and might get some grinding debris inside the filter. Using a filter cutter tool would leave no contamination.
 
I recieved the Summitt OFC to which you refer for Christmas. It works well enough. The only issue is on smaller filters like #7317, the filter doesn't reach the two guide wheels opposite the cutting wheel. Basically, the filter is held in place by the metal bar between the two wheels.

Again though, I've cut open several smaller filters and it works with several turns of the filter.

Sounds like they should have put the two wheels opposite the cutter a little closer together, or made them larger in diameter so the smaller filters won't fall between them ... that's what it sounds like is happening.

So how small in diameter are the filters you are talking about?
 
The #7317 has a dia. of 2&11/16 in. and it doesn't hit. Nor does the #3614, dia. of 2&15/16 in. doesn't quite hit either, but very close.

Those are the two size filters I use. Don't disagree with your assessment, but slightly larger filters would hit the wheels.

Yeah, I thought the price was good too. The Summit oil filter cutter isn't super fancy like some, but it is well constructed (heavy duty) and works well. Have only cut one filter open so far (Motorcraft) and it cut it open with only 3 turns.

I used an air driven rotary cutter. No metal contamination from the can.

Impossible!

Do you see metal shavings?

It is impossible to cut open a filter with an abrasive wheel (includes diamond wheels), a saw blade, chucked up in an air powdered or dremel type tool without introducing contaminates into the filter. That's the plain truth. Nothing more. Nothing less.

And yes, I can see, what appears to be metal, on the top end cap near the left end of the flap you tore while Dis-assembling the filter.

Uh ok, the top end cap would not have collected metal since it was at the top of the can and I cut at the bottom of the can.

The end cap was damaged by my thumbnail on purpose to show that it was cardboard. I posted this image on another thread regarding the Nissan OEM filter to show that it contained cardboard endcaps.
