There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars).

Sharpening on the other hand is using an abrasive (natural Stone, silicon carbide, aluminum oxide, diamond, etc). In this case you grind the blade against the abrasive again at usually a 20-25 degree angle. This removes metal, if you remove it evenly, you can create a very sharp edge. There's usually different coarsenesses that can be used for sharpening. On a micron scale, 100* microns would be coarse, while 1 micron would be rather fine. Coarse removes more metal faster, can be useful for reprofiling edges or fixing damage to the blade. A fine abrasive will polish, and more keenly get the two sides together. This allows a sharper edge. Let me know if there's more questions.
*Edit: 100 microns not 10
