I have been using a 110 inside and outside a deer for a long time. Went with S30V and CPM154 when they came out a few years ago, simply because I can go from about 2.5 deer to about 5 from 420hc to the newer steels, before sharpening.
We field dress (gut) ours in the field very soon after we shoot it. Back at the skinnin tree we strip the hide down a little and put a rock under it and pull it off with the truck. (Al Buck described this method in one of his booklets, but not where I learned it)
Son in law still uses his 110 to quarter one but have noticed him going to one of the 121's to separate the hind quarters and back strap.
This year, with the Buck specials on the 118 D2 buildouts, I believe the son in law will lay the 110 aside when he gets to the skinnin tree and go with the D2.
I am anxious to put those to work. They are already out there with factory edges, just waiting.
Since we process our meat (including sausage) ourselves, back at the house, we use electric knives a lot. But there are 121's and 470's laying there as well.
The 470 is great during final processing but didn't work that well in the field with it's wider blade. Doesn't trim out a backstrap like a thinner bladed 121.
Not saying it won't work, the 121 just does a neater job and gets more meat.
I guess you just have to do what works for you.
If you pay attention, and have done a few, taking a 110 inside a deer is no big deal.
Now, a 110 is a clip blade. I have honestly tried a few drop blades and they absolutely don't work for me. I ended up more stabbing the meat/skin than slicing it.
When I am inside, it's like the clip is up and out of the way of the gut pouch till I want the edge to cut it all away to roll it out. When I am skinning, and I don't consider drops as skinners, the clip blade just works so much better for me.
The drops I tried, S30V Vanguards, I seemed to slice through the skin or stabb a hole in it when I would go to lay the blade to start a cut. and then it seemed that the drop ended my stroke sooner than I was used to a clip ending a cut.
I guess I was fortunate to have seen a lot of different people gut a lot of deer, taking the best tips from the processes that worked best for me.
So give me a S30V 110 and a 121 in the field and the 121 and 470's and an electric back at the home base.
