Why is it called a k 12 saw?

There is no saw known as a "K-12 saw." It's likely you've encountered a misunderstanding or a term that's not widely used.

Perhaps you're thinking of something else?

To help me clarify, could you tell me:

* Where did you hear the term "K-12 saw"? (e.g., a website, a book, a conversation)

* What context was it used in? (e.g., woodworking, construction, education)

* Can you describe what the saw looked like or what it was used for?

With more information, I can help you figure out what you're looking for.
