I own the Al Mar Mini SERE Operator.
It could have been my absolute favorite knife if not for one flaw:
The handle is too small for my hands.
Ok, so the Al Mar is 8" long, the blade is 3.75" which should leave 4.25" for the handle, except that the handle's usable length is smaller than that.
The handle has two grooves and the usable space on this handle starts below the guard where the groove is at its deepest and ends at its deepest before the "retention spur".
This removes about 1" of usable space which leaves 3.25"
The palm of my hand is over 3.5" wide...
The Al Mar Operator has the same construction but due to the handle being measured at 5.25", remove about 1" and you still have 4.25" left.
This one is absolutely perfect for me! It literally feels like an extension of my hand!
TLDR: if your palm is more than 3.25" it may not be comfortable. Shame because it was this close to being a perfect knife!
