{"type":"firestarter.listing","listing":{"id":"lst_JbtbrK4i","product_name":"Santoku Knife","category":"Kitchen Knives","description":"A universal kitchen knife, Santoku translates as “three virtues” and depending on your sources, either refers to it being great for precise cutting, chopping and slicing (even very thinly) or the fact that it is ideal for meat, fish and vegetable preparations. Slightly different from other Western-style chef’s knives, it is lighter to maneuver and constructed with a boxier shape that helps scoop food off of your cutting board well.\nFinely balanced, the broad blade goes effortlessly through vegetables, fish or meat. The blade is made of exceptional, high quality carbon steel. It is ground very finely and thinly in \"Solingen thin cut\" and finely polished by hand.
