Sudsy water or inattention may lead someone to grab the blade when reaching for other items, or for a drain plug. Also, the curved edges of the basin may bend the tips of longer knives. Knives are not meant to be subjected to a lot of lateral pressure. If you must store it in a drawer, cover it with a sheath, whether you use a durable plastic sheath like our BladeSavers or a cardboard sheath you create yourself. Always lay a knife down flat on your counter surface with the point facing away from you and never allow another object, such as a dish cloth, to be obstructing your view of the knife.
Safety starts with awareness.
If you don't realize the knife is there, it is hard to be careful.
