What can I say, this is THE BEST breadknife I have EVER had, it glides through even the toughest sourdough, the lightest pastry too. It's simply stunning, and razor sharp as with all Katto knives. I'm so glad ee have a 50mm chopping board to cut on or this would definitely make it through our worktop! I have thinly sliced very ripe tomatoes and fruit too. As always the ordering was amazing and josh even made sure it arrived on a key day by RM so we didnt miss the delivery while at work. This will not be my last Katto knife !!!
