Robert Welch Signature Knife Sharpener 1 "Rubbish sharpener" Mr mangan 27 February 2020 Paid £24 for this several months ago to go with a RW knike from you guy's. I thought it was me, but reading the reviews this sharpener does not work. As another reviewer stated, actually blunts the blade rather than sharpens it The staff member in Bromley sang its praises. Obviously a major design of manufacturing flaw. My 23 yr old sharpner is still far superior A note from the team Thank you for placing your review. I'm sorry to hear of your disappointment - we've sold this sharpener since 2010 and the reviews represent only a small percentage of the number sold, most are very successful for our customers. Please ensure the clear plastic guard is on the sharpener when you begin and you are holding the sharpener firmly on a flat surface. Draw the knife through the sharpener with 10-12 strokes back and forth from heel to tip of the blade, applying gentle pressure and maintaining the blade edge in continuous contact with the wheel. Wash and dry knife before and after sharpening. Other methods such as only moving the knife one way or removing the plastic guard before sharpening may hinder the effectiveness of the sharpener. I'll be in touch to help shortly.
