Yikes! I think I know what's causing it, but admittedly, it's a guess.
Even cheap knives are made from steel with a Rc rating of anywhere from the low 50's to the low 60s. In other words, harder than iron.
To scratch steel, you need something harder than steel--that's why my stones wear out, but diamond slurry polishes.
Since the scratch marks are in the same direction, my guess is that you are looking at repeat damage from a singular source.
You say you slip them into a wooden block. Either there's a nail in the block which was too long, or a piece of metal fell into the block and got jammed there.
I'd take a high-lumen flashlight and a magnifying glass and look into the slots.
But here's the bad news--if that's the case, the piece of steel is jammed in there. If so you might have to take a piece of coat hanger, flatten an end in a vice and bend it slightly to form a hook.
If you cannot get it out, that means replacing the block.
We should talk by PM. If you send me one of the knives--and trust me--I'll try to polish out the flat of the blade, and if I can get out the side scratches, then polish the edge.
...I'd like to tell you I've seen worse, but not recently...
...No matter where you are it's enemy territory...
