Really thanks to the auto-folding mechanism very convenient to open a great little knife and and close. But smaller than I would have thought actually perfect for your pocket. The blade is very sharp and the whole knife, including the stem, are very stable and handles play-free. The lock on the opening button is very simple and works perfectly, what accidental opening virtually impossible. I also have the great AK101 in black with part serrated blade, but the thing is a real whopper. Drum is the AKS73 the perfect match, you can take anywhere. Would I buy again immediately. Perhaps the larger model, as I assume that it has the same structure, just give greater :-)
