I've used one for a long time.
Hands down, one of the best knives made for its price point. The axis lock is superior, of course, and very smooth, and there is no need for me to go on at length. The handle is a bit longer than some people think is necessary, but it is comforatble and secure in a variety of grips (including, for me at least, pikal). The blade is fairly thin, but is tough due to being saber ground. Despite the said saber grind, the thinnest of the blade and the grain quality of the D2 steel make the knife and excellent slicer. The tip is nicely clipped and very sharp.
If the knife is at your price point and is the sort of knife you want, you won't regret buying it. I know many more expensive knives that will not compete with the AFCK preformance-wise.
