“En casa de herrero, cuchillo de palo” or “sartén de palo” or “cuchara de palo” translates to “in the house of the blacksmith his knives/spoons/pans are made of wood. An example of an English version, “In the shoe makers house, the children go barefoot” share the same point to be made. This is one of my Grandmother’s most commonly used proverbs. The second part of the saying, changes depending how strong the feeling you want the statement to convey. Obviously, if the hypocrisy/irony is so great, like a teacher’s child dropping out of high school, because the teacher spent so much time with their students, to the detriment of their own child, then you would say “Sartén de palo”, because having a frying pan made out of wood shows the greatest negligence in terms of an item a blacksmith could have in his home. If the harm were less, then you would say spoon, because a wooden spoon is not that bad. Wooden knife would be worse but not as bas as the wooden frying pan, because a frying pan would eventually catch on fire rendering it useless much like the teacher’s kid who drops out of high school.
Analysis: This is a Colombian proverb I hear often growing up about various family members and friends. Favorite Colombian past time is to tell stories about the misadventure of their friends and family. This kind of story telling is meant to be “teachable moments” so you do not repeat the mistakes of others. It is often told during dinner, which makes dinnertime a two-hour storytelling session because others would feel compelled to contribute similar examples relating to the proverb.
