Here you can see the effect when applying mineral oil.
I’ve had this since 2005 and move from San Francisco to Berlin with it. I oil it once every other month with a basic mineral oil, to restore the health and lustre of the board. Such a pleasure doing so. Take care of your wood cutting boards: scrub them occasionally and dry them with a towel to ensure they will have a chance to dry thoroughly.
Kitchen shears, pocket knife (from Apple, c. 2000) office type scissors made of a heavy steel (and for the left hand), and plant shears. All for different uses and materials, just like any other type of tool. See my talk about Tools at Creative Mornings, Berlin 2017.
