Actually, the Canal Street building was originally part of the old Ulster Knife Co. complex, which became Schrade after the Baers did some consolidation. That's about the only building left now, which also houses a window manufacturing company. (Canal Street Cutlery utilizes the rear building). The newer Schrade plant is of course still there, apparently the owners are having a hard time finding a buyer for such a huge structure.
In Walden, the only things left are the old Walden Knife Co./Keen Kutter buildings, which were converted to the Thruway Shopping Center many years ago. They still look the same though, especially when viewed from above. New York Knife Co is long gone, replaced by condos, The old Schrade plant is gone as well, now woods and a Dunkin' Donuts stand in it's place. Walden has gone from being the Sheffield of the West to having nothing to do with knives anymore, really a shame IMO. There are still signs that pop up unexpectedly though, whenever there's a very substantial drought, the level of the Wallkill River drops considerably, and you see remnants of the old grind wheels laying in the mud that were tossed out the windows of NYK Co. when they were too worn to use
Same for Napanoch (a mile or so from Ellenville), the old Napanoch building burnt down nearly a hundred years ago I guess, no sign of it whatsoever now.
