Wow...Four pages of this...
I can only comment that I have been using a Buck folding Hunter 110 since the early 1970s (I own two) and have had zero issues using it to gut or the more pleasantly appealing term "field dress" deer without any issues.
I start at one calls the solar plexus and make a small incision, I then take the knife, aided by its heavy weight and make a slight right hand turn at the deer's breast bone and pull upwards, using both hands on the knife, easily cutting through the deers rib cartilage, again thank you Buck Knives for making the knife nearly a half pound in weight for making this job MUCH easier, and then I run the cut all the way up to the top area of the throat.
We then start on the gut sack area and using our index finger under the nice sharp point of said 110 Hunter we open up that area where upon the entrails want to start spilling out.
At that point I go back to the wind pipe and cut it loose and start cutting and pulling loose the tissues that hold it to the deer all the way back down to the lower tract.
After removing this and carefully removing the last of the fouling intestinal and urinary tracts I then have gotten this vitally important and few minute job done.
I then get the deer back to camp and hang it up and start the skinning process using the same knife all over again, namely the Buck 110 folder ... A knife that I have performed this same ritual on deer for four decades and counting.
A fixed blade knife will work too but in my opinion the Buck 110 folder does it as well as can be asked for and again the people that thought this design through had to have been experienced hunters with the thoughts that a good field knife to be used on large animals had to be of decent blade length and a weight to help the hunter on those harder cuts, namely getting past the breast bone/rib cartilage.
Your mileage and experience may vary.
