- n. The little plant Maianthemum Canadense, its barren stalks having but one leaf. Also one-leaf.
Sorry, no etymologies found.
I'm old enough to remember the days when we had to shave with those cheap plastic one-blade disposables - you'd do less damage to your face trying to shave with broken shards of Nautilus shell, like a dull, witless savage.
This is a very basic one-blade razor that would be very useful for removing lint from a sweater, but less adept at catching thick facial hair and left me with neck-rash and one nick.
At first we were satisfied with one-blade razors, until it was deemed that two were better than one.
