AquaBlade long scrapers feature solid fiberglass handles. Instead of using glues that break-down like other scrapers, the AquaBlade handles arev-grooved from the side and inserted into the head of the scraper during the injection molding process. Under thousands of pounds of pressure the handle is fused to the head becoming a part of the molded piece.The AquaBlade is injected molded as a solid piece of plastic which keeps water from entering the unit while using. This means no hollow handles and drizzling of excess water when removed from the aquarium. And without trapped aquarium water inside the scraper it will never develop odors from growing bacteria.By utilizing virgin plastic in the molding process instead of re-grind or recycled plastics, the AquaBlade is much stronger and more agile than other scrapers. The first time you pick up an AquaBlade youll notice the difference it makes. It feels strong and durable perfect for work inside your aquariumWhite plasite allows you to see the scraper more easily through darker algae. This means you dont miss any spots the first time around the aquarium.The AquaBlade cyan blade was created by testing countless different types of plastics and plastic blends. The results are a special self lubricating plastic that is softer than acrylic, so it will not scratch acrylic*. Constructed of 316 stainless steel, the AquaBlade metal blade is both strong and rust resistant so removing that stubborn coralline algae is a breeze.
