I like my Dropped Hunter, it is a substantial knife with enough belly for all around use but still a useful point.
For another all-around pattern and general purpose knife, I like his #7 with an extra 1/4" of blade. It comes out about the same dimensions as the Dropped Hunter but I like the grip shape a bit better. The Hunter model(not dropped) has a little less point if you want to go that direction. The Lite Hunter is another great one with a bit slimmer blade than the #7
If I was only allowed one Ingram design for all my uses it would likely be the #7+1/4 or the Lite Hunter.
I got a Slim for my daughter and it's a beautiful little knife but a bit too slender for me through the handle. My #4 Bird&Trout fills my need for a more delicate knife.
I think the H325 and the Chukar are almost identical through the blade but the H325 has a squared off butt while the Chukar is more rounded. I got the H325 for my wife who uses it in the kitchen almost daily and loves it.
Here's the only group I could find showing some different models. Sorry for the horrible lighting and color. Left to right:
Slim(Amboyna), #7(Ironwood), #7+1/4(Ironwood), Dropped Hunter(Black/Green Micarta), #4Bird&Trout(Spalted Maple)& #3 Semi(Black Micarta)
Here's a Chukar(Black Ash) and a Hunter(Buckeye).
Here's a Lite Hunter(Spalted Maple).
