Need advice on large collection of German budding/grafting knives

[Cory C]

I've been spending the last month trying to determine what I'd like to do with a rather large collection of never-used garden (budding/grafting) folding knives made by P.Kamphaus in Solingen, Germany. Most of them are in their original factory packaging. I acquired this inventory of knives along with various other garden tools from a horticultural company in the Chicago area that went out of business about 10 years ago. From what I understand, P.Kamphaus is no longer in business and I've come across a few used Kamphaus Knives being sold on eBay, with sellers stating these knives are getting hard to come by. I have over 700 of these knives, in various formats. As someone who isn't very extremely familiar with the collectible knife industry, I'm looking for any advice on where to turn to initially, determine the value of my collection so I can make a determination of how I can go about getting these knives in the hands of someone who can use them, either individually or at even as a collection to a collector who would be excited to take on these seemingly rare knives. I welcome any and all questions and definitely welcome any advice at all! Thank you so much!
