Q: I would like to know how victorinox swiss army knife have designed their knives with ergonomics in mind. So that the knife works with the human body.

A: Some Swiss Army knives are reasonably ergonomic, some are too bulky and some too small to be called that.

They are hand and pocket sized which qualifies them somewhat...

Q: There seems to be two manufacturers of the same products? Which is better?

A: Victorinox and Wegner are sister companies. Both supply army knives to the Swiss Army, in a 50/50 agreement with the Swiss government. Victorinox is actually the older of the two divisions and therefore claims the "Original Swiss Army Knife" tag line, while the Wegner division claims the "Genuine Swiss Army Knife" tag line. Both companies are required to meet the same specifications for the knives supplied to the Swiss Army, so you can't really say one is better than the other I guess! Now, knowing a little about the history, I would guess that they probably both have similar standards as far as their watches go. Additionally, they are both comparably priced, both come with a 3 year warranty, and both are available at several US retailers. I'd say that if you were interested in getting one, just go with the brand that offers the style you like better.

Ok there you have it- I hope this helps!
