While dating mine I discovered the "Safety Can Opener" on you and my example was introduced in 1947.Here's an old (1936-52, and based on can opener, probably post-WWII) Imperial scout knife I picked up at a consignment/antique/junk store in Cedarville, MI on one of our August vacations to that village. First photo is right after purchase, second photo is after some cleanup effort (I doubt if I'll try to remove the "serrations" on the small blade).

I know Imperial applied for the patent for that can opener on November 7, 1944 and that patent was granted Christmas Day 1945. I have some Imperial knives that have "patent pending" stamps on them, so it's conceivable to me that they could have started using the new can opener as early as the end of 1944. It's also hard for me to believe that they'd wait for more than a year after the patent was approved to start using it. So I'm inclined to say the patent info dates my knife to the range 1946-1952.While dating mine I discovered the "Safety Can Opener" on you and my example was introduced in 1947.
Therefore, you can narrow the date of manufacture from 1947 to 1952.
FYI the blade takes and holds a keen 10° per side/20° inclusive edge.![]()
Imperial (and everyone else) started using the safety opener in 1944 when military procurement specifications changed to require the one piece opener. After the war, other makers outside of the Imperial brand companies went back to their previous opener designs or paid Imperial to continue using the design until the patent expired.I know Imperial applied for the patent for that can opener on November 7, 1944 and that patent was granted Christmas Day 1945.
