Spring-assisted Gravity Knives
Some civilian gravity OTF knives have a small helper spring to kick out the blade. This partial spring drive is not sufficient to classify this type of knife as a switchblade, because it does not drive the blade out to full lock.

Famous quotes containing the words gravity and/or knives:
“Here I sit down to form characters. One I intend to be all goodness; All goodness he is. Another I intend to be all gravity; All gravity he is. Another Lady Gish; All Lady Gish she is. I am all the while absorbed in the character. It is not fair to say—I, identically I, am anywhere, while I keep within the character.”
—Samuel Richardson (1689–1761)
“I am the love killer,
I am murdering the music we thought so special,
that blazed between us, over and over.
I am murdering me, where I kneeled at your kiss.
I am pushing knives through the hands
that created two into one.”
—Anne Sexton (1928–1974)
