When trying to design a hunter you need look no further than your kitchen.2 knives in the drawer or block work great,the Butcher knife and the narrow bladed slicer with a slight curve,These have been used for meat proccessing with slightly any changes in 100 years or so.the narrow bladed knife works great to skin with and slicing the meat off the bone,the butcher knife will do it all,from skinning to splitting the rib cage to working in between the pelvic bones and cutting the tenden and releasing the legs off.
I have a hanger in my shop and all the neighbors here use it as the shop is warm,we have tested allot of my knife designs on deer here and have figured out that the 1/8 inch thick blade works best and is plenty strong enough.Length of blade depends on the hunters taste as I have seen them skinned and gutted with a 2 inch blade all the way up to a 8 inch blade.A deep belly on the front works best as it gives more cutting area when skinning.If you slip your finger behind the point when cutting the hide to gut you dont have to worry about cutting anything you dont want cut so point preference is also determined by the hunter.I rip the rib cage open with my skinners and have never used anything to hammer it through,just hang the deer by the back legs,use the back of the edge by the guard and point the knife down and you can just push it through the ribs with little resistance,this keeps the front edge sharp for skinning.Ring the back legs at the pelvis and you can go all the way into the pelvis joint and use the point of the knife to reach in and cut the tendon and the back legs will come off,also at the knee joint just use the back edge of the knife that you used for the ribs and you can easily cut the joint off without a axe or saw.
I have done this and my friends have done this with 3 inch blades and never had to sharpen the knife on a deer and we have done multiple deer at a time without sharpening,I prefer a 5 inch blade with a nice clip and sharp point,the length just makes skinning faster...
I use forged 5160 on my knives and have no rust problems even in rainy weather,of course you have to keep it cleaned and oiled up.
The best way to design a hunter is to look at what is available at your local stores and ask at the guns shops what the hunters carry,or talk to guys that hunt allot and ask what they preffer then make what you think will be the ultimate hunter and test it out,you can slice roasts and slice the skin off hams as a test till you get to try it on the real thing,then keep adjusting it untill you make the perfect hunter for you and your buddies.Testing is the key,lots of testing.....
Most hunters just want their knife to stay sharp through 1 deer as most states have a 1 deer bag limit anyway,here we have a 10 deer limit and I have had guys do all ten without sharpening their knife (at least that is what a few have told me).Allot of guys now days only quickly field dress the deer here and then take it to the butcher shop for proccessing and thus never cut a bone or anything but the first incisinon to gut the deer so they dont need anymore than a small pocket knife.
So ask around,make some designs on paper show them around then make a couple and TEST,you will find your answer to what a hunter is quickly this way,just remember every guy has his idea of what his perfect hunter is just like his perfect rifle setup
Sorry to be so long winded her,and take this as just my 2 cents worth,make sure and show us what you come up with.
Good Luck,
