Everyone knows that mustard weeds, thistles, and grease weeds are a fast-growing and tough nuisance, and we are experiencing many more. These stubborn weeds inspired us to develop the WeedSharks line of products! A reliable attachment to the consumer’s gas powered trimmer machine, with replaceable accessories. Various prototypes were tested, plastic and metal alike. After many tries we now have developed a platform that will include versatile blades that work well in a host of applications and are replaceable.
