Tweener sized knives...
So approx size range 4.3-5.5"... but not models that would be considered full size within that range (bk2 & 10 are 5.25", but definitely full size).
That rules out my mischief of RMDs. Tweener size - while great, and useful - is awkward in that I generally prefer to be more discrete about fixed blade carry. I have several favorites in the 3-4" range; but relatively few over 4" see regular carry... and my woods time has been extremely limited of late.
I'll add the image(s) later this morning
(No, I'm not just finding this...I'm just finding time to participate)
