Try many millenia. And not just hardwoods.

Go to leevalley.com and seach <scrapers>

Btw, the individual pieces of grit comprising sand paper is each a
miniature scraper... but no sandpaper can smooth (and/or dimension)
wood surfaces as well as broad edged scrapers. Sand paper should never
be used on woods that will be used for foods, especially not on end
grains... the wood will load with grit that will later release into the
food... no steelwool either.
