I just got my 58 MM BBK in today, and was looking at it and noticed a couple of things:

There's some black sealant type junk around the edges of the blades. Should this be cleaned up or left alone.

When actuated, the blades feel sticky from the fully closed position. Anyone else have this problem, and is it something to worry about?

Lastly, the BBK engraving on the blades is on the bottom half, and upside down. Did anyone elses come this way?

Overall, seems to be a nice piece. We'll have to see how it performs.
