What is the purpose of the small protrusions extending from the blades of the Ingenuity Mars helicopter?

I googled and googled, but couldn't find an answer.

I know nothing about helicopters (Other than riding a few in my Army days).

I came across this forum randomly and figured someone here might know.

I've attached a photo.

Cheers,

Dan K.

Just a guess- mass (weight) balance, to offset the torsion load of the weight of the blade feathering axis.

From an article and drawing in the magazine Popular Mechanics (can’t provide link as it is a subscription only), they are ‘weights’.
