I was fortunate to come across a heretofore unknown variation of a Pressbutton Knife Co guardian in the size of a PB "Buisness". I would be interested in any comments as well information regarding its manufacture, such as any catalog reference or any knowledge of the existence of another you may know of. Note the lovely "Guardian" etch.

Named the 'Guardian' from the Press Button Knife Co. patented in 1892 and designed by George Schrade. This model, with nickle silver fixed-guards, was only made for a few years and is very hard to find. This knife is in exceptional condition and a true beauty to look at.
