Up for auction is this maybe a one of kind or at least a very scarce June 6th 1893 patent hand forged Brass folding pocket knife invented by Vandalia Slator of Hunts New York. I found the patent online and will include a paper copy but have not been able to find another like it. It is stamped U.S. Navy, but not sure if the owner had it stamped or if it was made for the U.S  military during the Spanish American War or World War I  ? The knife is in a very good operating condition, and it's a 6 3/4" when open and 3 3/4" when closed.The knife  has what appears to be a full 2 3/4" blade that doesn't look to have been sharpened but is sharp and the knife hasn't been cleaned and is as it was found ! Please use the photos as part of the description, and if you have any questions, please don't hesitate to ask. I will combine shipping, but please DO NOT PAY until you are finished with all your purchases, and I send you an updated invoice with the new shipping charge and them all combined.
