Well, what I use will be a let down for the guys that like those fancy custom knives that cost several hundred dollars apiece.
Get yourself a Forschner 6" boning knife, I like the straight edge, about 20 bucks, I'll put two in my pack for an elk...
Some prefer the curved boning knife.
For processing steaks I use a fluted Victornox/Forschner 10" steak knife.
(Forschner Fibrox? Granton Edge Cimeter Knife)
About 70 bucks
I've used the unfluted too
About 35 dollars.
These knives are pretty much standard issue among professional meat cutters, very rarely do I see anyone use anything else.
Get a good sharpening steel to bring the edge back when it rolls over and use it often...
I like a fairly coarse one, other like the fine grained ones.
When the sharpening steel fails to bring the edge around run the knife over a 3 way oilstone at a 20 degree angle using the fine side.
Once the knife loses its edge to a more severe degree use the coarse then medium then fine to put a new edge on it, again strictly keeping to a 20 degree angle.
Learning both the muscular anatomy and exactly where the bones lay in an animal will get you a lot further than just a sharp knife as far as speed in producing quality cuts, it just takes practice.
You can get everything from knives to sharpening steels to grinders, power saws & tenderizers here...
