I’ve got a Cutco serrated fixed blade I highly recommend. Forever Guarantee…etc. It slices through the ribcage easily and it is SCARY SHARP! It’s easy to clean and I’ve had it ~10 years…10+ deer without sharpening it.
I have used a old cheap Sharp 300 folding knife. It works fine but a little hard to clean.
This year I used my Swiss Army pocket knife since I packed my Cutco in the wrong pack I keep it sharp so it’s no problem cutting I just didn’t do the rib cage. I Don’t recommend it since it is even harder to clean.
I do pack a Wyoming zipper knife for opening them up clean and fast. You have to love the zipper action.
I also use a cable saw for the pelvis although I just picked up a Sagen Saw after the season for next year.
For actual butchering time we use a Buck skinning knife to get the hide off. And Chicago Cutlery for all the boning and steak/chop cutting work. The sharpen up fast since they seem to be rather soft. We usually touch them up after every quarter.
Whatever brand you get just make sure you keep it sharp!
Ferny.
