guess what cutting tool made this cut

[Willy]

I dunno, it almost looks like it has three facets to it like it was cut in three passes. Then again it also has a straight grain or brushed surface on top of those facets. Almost looks to be finished with an in line sander.
I know I've obtained some really nice finishes on steel using of all things, a random orbit sander.

The finish isn't consistent with a rotating face cutter. I enhanced the image and it could be a slabbing cutter or a shaper.

Side cut on an end-milling cutter?

[Carld]

Horizonal mill with a cutter as wide as the marks indicate???

Ok I'm off to work, but just wanted to say it wasn't done on a mill or a shaper. I'll check in during lunch and give you the answer, I think you'll all be surprised what tool actually made the cut.

"the cut". Bandsaw.

[A.K. Boomer]

I think Evan's either right or close - Its a cut -- but from what?, it cant be a typical saw due to the straight line of the cut and lack of a regressive arc so that is why I believe the bandsaw guess is in the ballpark - still Id like to go further out on a limb and include the power hacksaw -- depending on design (and there were many) I seem to recall a few that lifted the blade and drive rack up at both ends and then rested it back down on the work piece level, this could also give the results seen in the pic - and yes the position of the piece looks as if it was changed about three times... but the cutting grain is really all in the same direction --- so the "blade" picked up a crumb for a bit.
