wood must be quite hard and have a decent edge which is sometimes difficult to source in small 1 time tools
as an example of "good wood" scraping, my dad is a piano tech, I work for a piano manufacture, at my last job a guy was talking about how the head gasket of his car was leaking, and how the "Internet" suggested a hard wood scraper
so I cut a scrap chunk of pinblock from my dads shop (pinblock is inches thick cross grain maple veneer, saturated in epoxy and pressure laminated engineered wood dating in design for at least 100 years used to hold the string tension on the tuning pins (screws) an average of 18 tons over the hundred + of (just over) quarter inch thick high tension steel pins)
that just held up to scraping a head gasket off of a ford taurus wagon
:O
course with a belt sander to renew that edge it would last 3 generations
