Joseph Joseph Bladebrush Knife Cleaner Green 5 "Great for what it was designed for and ...." Helen 28 November 2017 Our carving knife is a huge old-fashioned thing not dishwasher proof. I usually finish the day on a Sunday after dinner by washing up the last few things and slicing my finger on the knife. This will prevent that once and for all! But when I bought it, I had a sneaking suspicion that it would clean something else too. I've asked Lakeland to come up with something to clean the shower hose with, and this is so nearly that object! The bristles get right in to the places nothing else reaches. If it was a bit smaller, so it could spin down the hose it would be absolutely perfect.
