436. Haven't been able to verify what this is,
here are the guesses so far:
-note holder
-static electricity dischargers
-puncture test tool
-grandfather's clock mechanism
-weights for the scales of justice
-for electrical experiments
-durometer
-tester for finding the hardness of optical pitch
-spindle for paper
-for making indentations in metal
-standard lightning rod balls and needles
-for gravity experiments
-desk decoration
437. Golf tee
438. A froe, this tool is used for splitting out shingles and barrel staves. The blade is intended to split rather than cut, it's struck with a froe club after being placed along the grain of the workpiece.
439. Motion detector, found mounted on a stairway wall in the building where I work.
440. Hiller Atom Ray Gun
441. Lawn mower
Here is a similar one called Montamower, thanks to William for sending this ad to me:
