I think a rewording of this would make the question on-topic, useful to all including the op. An excerpt from the question at this time:
People in my community wood shop don't always remember the difference between types of saw blades for the table saw and band saw.
While having a visual aid for this is important the root of the question is really
How can I recognize the different blade types
I think that we can reword this question into at least one question where it is just asking about the different table saw / circular saw blades types. (two different blade types might require two questions)
Once the OP is aware of the different types he could, on his own, create his own visual guide with all the information that he would have learned from the answers.
