The Dreamfarm Oni All-In-One Kitchen Knife really does it all. This kitchen gadget slices foods like tomatoes and bread, which can be tough to get through with non-serrated knives. However, when you flip the Oni knife over, you can use the backside as a spreader for condiments. When you’re making your favorite deli sandwich for lunch, you don’t need more than this all-in-one knife to do so. In fact, this multipurpose kitchen knife even has a plastic slicer at the end of the handle. So when you’re done assembling your sandwich, you can slice your plastic wrap to go around it. Or, if you’re prepping vegetables to roast in the oven, use this plastic cutter to slice parchment paper so they don’t stick to the pan.
