So What are the Many Differences?

Here are these twain Victorinox Explorers again.  What 's the difference?  Easy that.  Proceeding clockwise, from the upper right (the images may need enlargement) we observe these differences.  Which are, by the way, not same differences.

1.  Grooved (top) vs. not grooved corkscrew.
2.  Key chain ring reversed top to bottom.
3.  Silver metal vs. gray plastic tweezer top.
4.  An extra tool, the multi-purpose hook, on the bottom knife.

There are other differences too, but these are the most prominent on the back sides.  So, the moral is, Swiss Army knives may come in many iterations, like warblers or maybe sparrows, and thus,  provide the fodder for a potentially interesting hobby.

By the way,  the top knife is a much older knife, pre 1978, is in better condition, and was way cheaper to acquire on EBAY.
