AquaBlade long scrapers feature solid fiberglass handles. Instead of using glues that break-down like other scrapers, the AquaBlade handles are v-grooved from the side and inserted into the head of the scraper during the injection molding process. Under thousands of pounds of pressure on 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 you’ll notice the difference it makes. It feels strong and durable - perfect for work inside your aquarium.
