Victorian "The Electric Knife Cleaner" Circa Late 1800's

Now here is an item that is seldom found these days...a "must have" for those decorators of Victorian Kitchens. The Cleaner is marked .... "WALLWORKS PATENT"....and ...."The Electric Knife Cleaner". It is made of cast iron with pieces of cork on the inner. There are holes in the top where I think maybe some type of cleaning fluid was poured and the knife was inserted on the side between the cork slabs and moved back and forth. Measures 4 3/4" in length. 3 1/4 in width, and 2 1/2" in height.
