I wish i had discovered this tool before, i was starting to despair with the state of my hob, no amount of elbow grease was working. Its so cheap but great. My hob looks brill. When you need to apply extra pressure, turn the scraper over so the bolt is facing the other way, that side of the blade is sharper (prob makes no sense!). It was dispatched the day i ordered and i received it 2 days later. Very pleased a great investment. Thank you!
