For years there have been mail box posts in front of houses. Since the invention of the weed-eater in around 1972, the wooden mailbox post has been getting whipped up by the plastic weed-eater line. The grass grows next to the mailbox post and when the weed-eater trims the grass around the post it can't help but strike the post with the weed-eater line. This causes the post to get chewed up, and whipped away. The WS3 is designed to eliminate this problem.
The WS3 is designed as a strong series of interlocking side pieces the have folds in the opposite direction of each other. Which each fold connects together with the next fold on the next side, so on and so on until WS3 is one complete rectangular unit surrounding a wooden post, protecting it from weed-eater damage.
WS3 is generally made of galvanized sheet metal, but can be made of any other material that is rust resistant and strong enough to withstand the abuse caused by a weed-eaters line striking it. To make a WS3 you simply cut to shape any number of sides, as long as the sides edges have folds in the opposite direction of each other (see
