Having good knives to make meal times a breeze is essential when cooking in the kitchen, which is why we’re so excited to bring you the Wiltshire Staysharp Duo Set review. The Wiltshire Staysharp Duo Set is available at Wiltshire.com.au, Big W stores nationally and selected independent stores. More about the Wiltshire Staysharp Duo Set Review Staysharp knives have a clever self-sharpening system so the knives stay sharp! You can ensure no more blunt knives. Simply insert and withdraw the knife from the scabbard for a sharp knife every time. All good things come in twos, like this Wiltshire Staysharp Duo Set. The Santoku Knife is comfortable with mincing, slicing, dicing or chopping; and the Utility Knife feels right at home cutting small fruit, vegetables and herbs.
