Meaning of “See through three inches of a cutting board”
“See through three inches of a cutting board” is a proverb that describes someone with extremely sharp insight into the true nature of things.
It means having the power to see through even a thin cutting board that’s only three inches thick, right to the other side.
This represents the ability to understand not just surface information, but hidden truths and the essence of matters.
This proverb is used to praise people who can accurately grasp someone’s true character or the real situation.
For example, it applies to someone who can read a business partner’s true intentions or quickly identify the root cause of complex problems.
In today’s world overflowing with information, the ability to capture the core of matters without being misled by surface details has become increasingly important.
This proverb is understood as words of praise for people with such deep insight and analytical ability.
Origin and Etymology
There appears to be no clear written record of this proverb’s origin, but we can make interesting observations from how the words are structured.
“San-zun” refers to a very thin thickness of about 9 centimeters. “Manaita” means a cutting board used in cooking, a tool essential to Japanese kitchens since ancient times.
This proverb likely arose from the idea of being able to see through to the other side of a cutting board that’s only three inches thin.
A cutting board is a tool cooks use every day. Everyone sees the surface, but the underside is normally hidden from view.
However, someone with a truly discerning eye can guess the condition of the underside just by looking at the surface.
This may reflect the wisdom of the craftsman’s world.
Also, using the specific number “three inches” adds emphasis, meaning “even something this thin.”
If you can see through the back of a thin cutting board, you must have the power to see the essence of anything else.
This is how the meaning likely developed.
In Japan, where craftsman culture took deep root, this proverb probably emerged as an expression praising the sharpness of observation that sees not just the surface but the hidden parts as well.

If this is a combination of “san-zun” and “manaita” (cutting board), three inches equals about 9 centimeters.

The thinner a board, the higher its light transmission rate becomes, making information from the other side easier to obtain.
