Hi,well, test done. The result is not so bad in my opinion. Of course not as clean as the "old" design can opener work. It looks like a circular saw disc, regular.So I get the same result than you get.As it does the job, I cannot complain, and as I'm used to opens can with a combat knife, the result is definitely nicer because more regular, but not as different as with my Kabar knife.And by the way, I was using the "regular method" : going clockwise. press the tool on the can, make a cut of about 5-6 mm, then move the opener 5-6mm clockwise, press to make a cut, etc. It was fast, efficient.
