So I stopped in and had a look today. While it is only 1 decent sized room, the amount of history collected is impressive. While there is an extensive collection of Schrade knives, of all generations, that is not all. They also have jigs, blanks, dies, etc from the various factories over the years.
In addition to Schrade, Napanoch, Ulster, NYKC, Imperial is also represented. And finally they have a very nice collection og BSA knives, mostly Camillus. Definitely worth the stop. They have been working towards opening day for six years now.
PS: They aren't billing it as a Schrade museum. They see it as 150 years of knife making.
