For your consideration is an antique International Silver/1847 Rogers & Bros silverplate master butter knife.  This is the Navarre pattern and has the twisted handle.  It is 6 3/4" long.  It does have a small chip on one side of the blade as shown, but not really seen when using.

I have recently acquired a very large estate.  There were many jewelry and collectible pieces.  I will be listing many more items in the next several months as I dig thru all the pieces.  Thanks for looking.  Check my other listings for more jewelry, vintage, antiques, collectibles, clothing, fabrics and holiday items.
