All About Pocket Knives

I'm looking for any information on Mcknight Cutlery Co. . I have a couple of their knives and have been hunting for history on the company. In John Goins book it shows Mcknight & Co. 1891-1892 in New York,N.Y. In Levines book it lists Mcknight Wolesale Hardware Co. Wichita, Kansas.1891-19??. My knives are tang stamped Mcknight Cutlery Co. Wicita,Kansas. I searched thru the local newspaper microfilm for any record and found ads for them in 1891 and 1892. I found a old postcard on ebay recently from Mcknight hardware, cutlery and tools in Allegheny, Pa. dated may 31, 1893. I,m thinking this might be the same company. Maybe they moved from kansas to Penn. in 1893? Any one have any information.
