I used to turn my nose up at all of the Imperials I've seen, and really wished I hadn't. Most of them were the plastic handled junkers sold for a few bucks at most of the junk stores I've haunted for knives in the past. Most of the scales were broken or falling off, the springs were either seized shut or loose, and the blades were heavily patina'd or so dull butter wouldn't get out of their way.
Then I saw my buddie's Imperial knife, a beautiful scout knife carried by his drill sergeant in the Marines. Then, I saw a really nice looking stockman that a local knife dealer had at a gun show, I wish I would've traded the knives I had at the time and paid the damn $20 bucks, instead of dickering with the dealer over the price, it was a great looking knife. These two were much different than the junkers I'd seen bearing the Imperial name on them. No plastic or loose blades on these.
Some of the blades on recent knives from both companies, and on older Kamp Kings etc, looked and felt like they were made of sheet metal.
I am going to the local gun show this Friday after work to see if I can do a little knife trading with that same owner for that old Schrade.
So, yeah, both made some great knives, believe it or not. I can't find any of the old Imperials or Colonials at my junk shop haunts any more. I guess when I got the old Remingtons, Voos and other assorted knives, I used all my knife luck for the next ten years!
