Third installment of Hand Tool Forensics . See if you can identify the operation and hand tool that produced this waste. Akin to mechanisms of injury. Seeing an end result and determining the cause.
The ends were sawn and waste removed with a chisel. The waste gets finer as you get closer to size. There are also crumbs that I would guess come from chopping end grain. Some of the pieces appear triangular. My first thought was dovetails but the angled waste could just be chisel angle.
I did almost the exact same thing putting the uprights into my file till just last week, so the leftovers looked familiar. And I free-handed a backsaw as well. Cutting all the slots for all the files gave me a lot of practice sticking to my line.
Edit to add: the chunks were too thick for a dado plane, which was my first thought, but I'm pretty sure you don't use one of those very often.

I had a feeling you would get this one. I find it easier just to chop out the waste with a chisel when cutting dados. I will use a rebate plane on rebates, though.
If I've got a dado plane in the right width, I'll use that, but that's just ¼", ⅜" and ¾" for now. For half, I use a chisel, but I'm keeping my eye open for a good half-inch dado plane.
Scrub plane (with an aggressively cambered blade), cross grain.
