If you just want that look buy reclaimed lumber OR take an old high speed steel blade for your table and bend one tooth in maybe 1/64" or less...

Don't saw too slowly or it will defeat the purpose.

These marks come from old circle saw mills that had poor quality control on tooth set and a slower RPM than modern saws.

It just looks like the wood was ripped on a table saw with a old fashion steel blade. They cut rougher than carbide blades.

I agree with Steve Neul, get a steel blade with a low tooth count, skim the wood on your table saw with it.

Looks like you could do that with a handheld angle grinder.

Speaking of angle grinder, I saw a angle grinder wheel at harbor freight that had chain saw cutters on it. That might work.

Or here's a slick and easy idea - bend one tooth on a steel saw blade!

It's not complicated and it doesn't have to be tedious.
