The Manix is very close to my ideal heavy-duty outdoors folder. Also in the running is my Al Mar SERE 2000. I never thought I'd find a folder which might one day displace the S2K, but this is looking like it might be a close race.
I bought, then sold on, a Spyderco Military. Although it was big, the blade tip was too delicate to convince me that it would stand up to a beasting.
I bought, then sold on, a Benchmade AFCK. Although it was big, the ergos just weren't right for me.
I don't think I'll be selling the Manix.
"Problems" so far? Mine (bought second-hand) has a trace of fore-and-aft blade play; also, the blade is a millimeter or two off-centre when closed. Neither of these concerns me.
I like it.
