This is an awl. Use it to punch holes!
Nouns for physical objects occur most often in Analogies questions. So if you saw a question that began AWL : PERMEATING, you would make a sentence like “An AWL is a tool used for PERMEATING a substance” or “A 1 is a tool used for doing 2 to a substance.” Then you’d search for the answer choice that works best in the 1 and 2 spots of the above sentence.
Which of the following two answer choices would be your final answer as a match for AWL : PERMEATING?
A) BLENDER : HOMOGENIZING
B) VARNISH : SEALING
Many Analogies questions are easily narrowed down to two choices, when difficult decisions have to be made. It’s true that a blender can homogenize and varnish can seal.
Go back to the relationship sentence. If you had written “An AWL is for PERMEATING” or “A 1 is for 2,” both choices seem correct! But a more specific sentence should include that an awl is a tool for permeating, and also that the permeating is done to something else.
Is a BLENDER a tool? Yes. Does it homogenize another substance? Yes.
Is varnish a tool? No. This is not a valid match. (Something that meant “varnish applying device” in place of “varnish” would’ve made the choice a match).
I wonder if leatherworkers ever say “Go out there and give it your awl!”
