Ok, so I noticed that my little brother keeps a kershaw shallot under his pillow at night. it has no saftey lock like the leek scallion and chive do. but the spring is stiffer on the shallot. anyway, is it safe for him to keep it under his pillow like that? should I tell him that it could spring open in the middle of the night? what are the chances of it springing open? thanks guys.
