There are a bunch of different oil filter cutters out there You have to remember(or know ) how a oil filter works so you won't be worreid about the shavings from the cutter confusing you when you inspect them I cut the top off of the canister and then cut the element loose form the center core(both ends ) and then split it longways in the middle, unroll it and look very closely in all of the pleats as well as the rest of the filter Mopar oil pumps make the oil flow through the filter from the outside edges into the pleated paper and then exit into the center of the oil filter before being pump into the motor Most of the oil filter cutters I have seen and used are like a pipe cutter, very little debris from cutting the filter canister open Buy one and use it always on every oil filter change
