I bought one roll of the light wire years back. It likes the shape it starts out in. A wire gate is a slinky of sorts. I am thinking of using some of the Gaucho wire on some rad fence, it's some cheaper, and as you said, the finish wears well.
Two barb, or four Barry?
A wire gate is not a gate at all! It is a death trap awaiting the unwary. To compare it to a slinky is unfair; a slinky, while one of the most totally useless objects ever devised by man, at least isn't malevolent.
