Hi Robert. The eariest style of can opener was a small Sharp blade with what looks like a thumb stud but is actually what you use as the lever along the edge of the can. Bernard Levine has posted most of the patent dates of these devices on his ID forum. If anyone is interested in doing a forum search I'm sure it could be found.
Best regards
Robin
I've used the opener on the regular RR camp knife ( the type you described above) , it's a bit of an effort , but it does work.
The blade held up reasonably well, I resharpened it after opening two cans.
