Not to be juvenile, but I firmly believe that "computer log processing" is much more comparable to sewage treatment than converting trees into lumber.

Maybe you can't get funding from people who name things after middle earth magic rocks if you call your system "sludge strainer" ?

Angle grinders are useful when working with pipes, though.

Slice, no. But look up "wood carving disc" or "wood shaping disc" for some angle-grinder related crimes against woodworking - lots of power, but you'd better know exactly what you're trying to accomplish. (Besides, after 3+ decades of command-line-enhanced log processing, you can assume that a fitting or obvious name has been used three or four times already :-)

There’s already a DFIR log tool named chainsaw: https://github.com/WithSecureLabs/chainsaw

"Sawmill"? https://en.wikipedia.org/wiki/Sawmill (or maybe "crosscut"?)
