The bunker is the ultimate bad ass as its a multipurpose knife that sits between the nakiri and a gyuto knife. The word “bunker” means “culture” its a very versatile knife and perfect if you want a slightly wide blade compared to the santoku. The blade’s rocking point is around the same place as a santoku but the big difference is the pointed tip. Its sharp scalpel point is perfect for cutting small shallots but has the belly too chop larger foods and so is the perfect addition to any collection.
