Introducing the O.T. Prep Knife from Messermeister’s Oliva Elite Collection, created in collaboration with chef Olivia Tiedemann. Just like Olivia, this knife is edgy, bold, and built for the grind of everyday prep. Forged in Solingen, Germany from high-performance 1.4116 steel, it’s sturdy enough to handle the power moves of a chef’s knife yet thin and agile enough to fillet fish with finesse. Its Mediterranean olive wood handle brings natural beauty and a comfortable grip, making it the perfect companion for long prep sessions. Quickly becoming Olivia’s go-to blade, the O.T. Prep Knife excels at everything from breaking down herbs and vegetables to slicing proteins with precision—making it the ultimate workhorse for any kitchen.
