P-38

https://en.wikipedia.org/wiki/P-38_can_opener



The quintessential manual can opener, the P-38 is a claw. It is interesting that the hook and cutting edge are not in the same axis. They are perpendicular to each other, which positions both at the perfect position. The hook meets the lid at a right angle, grabbing onto it wonderfully, while the cutting edge tip contacts the lid right behind the rim, and the perfect angle to pierce into it.



Piercing was easy. The P-38 is designed perfectly to engage the can like it is supposed to.
Comfort is relevant I think. It does not make much sense to expect amazing ergonomics on something this tiny. It was not uncomfortable, and after only a few cuts, I was already used to the action, and was able to rock the can opener up and down, cutting with no issues. I never felt the slight hint of it jamming or slipping of the rim. In fact, I let go, and the can opener sat frozen in position. It was not stuck or anything close to that, just sitting comfortably on the rim, thanks to the excellent angles of the hook and blade. Tracing along each previous cut was extremely easy and surprisingly fast, once I got used to the action.



It created a rather jagged edge, and I noticed a few metal specs on the table. These are not like the metal splinters that other can openers have produced, though I would prefer no shavings at all.

I will test this again and maybe go slower, and see if I continue to get metal specs.
Has anyone else noticed any metal specs with this? :think:

P-51



The big brother of the P-38, longer, thicker, heavier. Using this was a very similar experience to the P-38.
Piercing was extremely easy. The shapes and angles are the same, and this also engages the can perfectly. No slipping, no jamming, and still sitting in place when you let go.


This was a little more comfortable. It is longer, and I got a better grip, and thanks to the blade being slightly longer, I got longer individual cuts. The difference in leverage is very noticeable and much more than anticipated. After only a couple of cuts, the action felt intuitive and I was able to cut the rid faster than any other can opener I have tested. Speed was not taken into account when using can openers for this thread, but the P-51 would be the winner. While extremely fast, the cut was consistent, easy, it never slipped or got jammed, or advanced off kilter. Most importantly, there were no metal shavings of any sort with this. It left behind a clean edge, less jagged than that of the P-38.

It may be heavier and larger than the P-38, but the difference in performance was very noticeable. It is still small enough for all sorts of kits, and certainly a fantastic companion to any multi-tools that lack a can opener or have a mediocre or unusable one.
I can not wait to open a can with this again. :salute:

I was looking forward for you testing them RP  :hatsoff: I think this thread would be incomplete without thwm.

Excellent results for such a "simplistic" design  :like:

I love the design. How can something this small be designed so well for its purpose, and perform so well? Does your multi-tool not have a can opener? Slip a P-51 in the sheath and you're set. :cheers:

You do a great job. I avoid long commentary because I would make and miss many more verbal blunders.

Fun indeed, thanks for sharing it  :tu:
The swivel-around-the-middle ones seem cool!

Makes me want to search eBay for vintage can openers now  :facepalm:

+1

It awlso keeps the lid and makes it easier to remove it without risking cutting yourself.
