That is a good find that you have right there. I like the aluminum scales and find them very sleek. It is comfortable as well. That AUS-8 holds a very fine edge.
The coating on the blade WILL NOT disappoint you! I sold one to my friend about 7 months ago, maybe more. He has done heavy cutting with it, and the edge holding is wonderful. Further more, he is always using it to open beers! He gets the spine under the cap and prys it off. He's had lots of practice, so it just pops them off now. But that knife looks like it is brand new! No scratches on the surface, nothing.
On a knife your size, you shouldn't find any trouble with the mechanism. On larger models, the liner can lodge too far over, thus making it very difficult to close. But even on those larger models, that's just a sign that you are flicking it out to hard. Use that flipper.
It's a good knife, and I readily endorse it.
