Quick tests
Verb-form test
Does “saw” mean cut with a saw, and does the sentence require a simple-past form?
If yes: Use “sawed.”
If no: If the cutting verb needs a participle, use “sawn” or documented “sawed”; if “saw” means perceived, treat it as the past of “see.”
Caveat: The cutting verb and the past tense of “see” are homographs with different inflection questions.
Examples
They sawed the damaged board in half.
“Sawed” is the simple past of the cutting verb.

“Sawn” is a past participle of the cutting verb.

Further guidance
Core difference
Use “sawed” for the finite simple past of the cutting verb; use “sawn” or documented participial “sawed” when grammar requires a participle.
Fast Test
First identify the verb. If it means cut with a saw, simple past is “sawed.” If “saw” means perceived with the eyes, it is already the simple past of “see” and belongs to a different paradigm.
Usage Boundary
Do not let the existing “saw vs. seen” question for the verb “see” absorb this separate cutting-verb task. Do not present “sawn” as the ordinary finite simple past.
