The following description was prepared by William Gross:
Perhaps a unique set of 4 boxed knives. Each of the different size boxes is carved with the image of the animals or fowl to be slaughtered with that particular knife. Usual decorative material on objects having to do with the subject of ritual slaughter is quite rare. There is another such object in the gross collection, gross #042.008.002, and one such knife holder in the einhorn collection. The inscriptions on these cases have to do with animals for which each knife is intended.
Bottom of the handle signed: Memel.
