I have a mini-Canadian, two mini-Skinners, the Bravo-1, and a new Highland Special. The Highland has a 4" A2 steel blade with Impala horn scales....nice medium-sized knife. The Bravo-1 is huge (by my standards...I do not own a Ranger, Scrapyard, or large Ontario), with 4.5" of A2 steel. I liked the Bravo over the Gameskeeper because the Bravo didn;t have a bolstered fingerguard... I prefer it without.
As someone said, BRKT knives are addicitive. If I had to recommend a "medium-sized" knife to you, I would say the mini-SKinner (12C27 stainless) or the A-2 carbon Highland SPecial for something just a little larger. I know the mini-SKinner is small, but I'm just throwing it into the medium category, probably at the very lowest end.
One thing about Barkies is, their handle scales are smooth....as in, lacking grip or texture. The Impala Horn is my first one with semi-grippy scales, but I imagine the Antique Stag (imitation), or the Sambar Stag or Bighorn Sheep would have a similar texture. Unlike many knife manufacturers offering canvas or linen Micarta that grips your palm and fingers, and even improves with moisture, the Barkies are well-endowed with epoxy or other resin, so they're very smooth. Their wood (maple, myrtle, elder, etc) scales are also finished very finely and smooth. You should bear that in mind.
You don;t say if you're familiar or not with the convex grinds. Be prepared for a slight learning curve keeping these beauties sharp. I say slight because, while it takes some learning, it ain't tough. My BRKTs are the sharpest knives I have and, believe me, I'm a beginner. I was whittling and hacking away last night with the new Highland on a piece of Mexican elder (not a very hard wood) and managed to take the razor out of most the 3.6" long edge. It was still sharp and would shave hair, but it lost its razor. Just a half-hour ago, I swiped it a few times on 2000 grit, stropped with green rouge, and now it's sharper than it was upon arrival.
Both site listed above are good for Barkie-hunting, with DLT being
by far my favorite. BUT......for a much more comprehensive idea of all the Barkies available, and
complete specs on every knife, visit the BRKT club site, and click on "Current Production" in the right-hand pane:
http://www.barkriverknives.com/home.html (You can;t buy knives here)
Even Bark River's own site (you can;t buy the knives there) doesn't have as much specification information. Their site is:
http://www.barkriverknifetool.com/
The two site might be both sponsored, run, or managed by BRKT, I don;t know.
I absolutely love and admire these Bark River knives, but you probably couldn;t tell that.
