In this episode of RECO, Rick Martinez puts Quiddity’s top 10 chef knives to the ultimate cutting test. The first round tests if the knife has the sharpness to cut through a standard piece of paper. Next, can it withstand slicing through a hard butternut squash? The remaining knives advance to carving a slippery, squishy tomato in half. Finally: an onion. See which one takes the top spot, and which one has a heel so sharp a gentle touch can nick a finger.
