Kris,
I
love the #25s, but they are definitely on the small side. Or at least, I imagine they may seem so in most men's hands.
I took some quick pictures to demonstrate, with other knives as size references.
Note the comparison with a Boker barlow (first picture, a more "standard" 3 3/8" barlow length), where the end of the handle falls in/on my (women's medium) hand when in a roughly in-use position.
GECs:
Other possibly known quantities, for further comparison (these were quick pictures; sorry I didn't catch the thumb fuzzy before it was too late!):
Case Medium Stockman
Case Mini Trapper
Case Peanut (my hand's squunched down more on this one, so the comparison is not as direct)
GEC White Owl
Hope this helps!
