Chopping Through Bone When Butchering

I have been butchering animals for many years... mainly game animals, but occasionally I've processed farm animals.

I first started participating in Bladeforums about ten years ago. One of the most useful things I've learned here is that a carcass can be split down through the spine by batoning a blade down through it. Prior to that, I'd either chopped or sawed the backbone. It is hard enough to keep the cut straight while using a cleaver or axe, and it also creates the by-product of a whole lot of nasty little chips of bone that can end up in your meal. It is also difficult to keep a saw on track... and the bone sawdust isn't that pleasant in your food.

I wish I can remember who the Bladeforums member was that told me about a hunting guide who split a moose carcass by batoning his knife down through the spine. I'd like to send him a cyberhug and tell him how useful this technique has been to me and my family. If you read this.... thank you mate. It was a very helpful tip.

I don't generally split game animal carcasses. Mostly I cut the meat off the bone on the hillside. However when I have to cut up a sheep I might like to create chops and this involves cutting the spine.

My brother likes to feed his family pork ribs... and this involves splitting the backbone also. He was pleased to learn about the batoning trick... and I gave him a machete to use for the job.

I have generally used the same 10" Tramontina machete every time I've split a carcass. Over a two day period, I once butchered nine sheep for a relative. I could not see any damage on the edge of my blade.

Recently I killed two big pigs. It was a wet day, it took a long time to cut the meat off the bones on the damp hillside... and I wanted to save the tusks. If the conditions had been a bit more leisurely and pleasant, I might have tried to cut out the complete bottom jaws of the pigs. But I wanted to go home. I skinned the front end of the bottom jaws, then hacked through the jawbones with my machete. (These jaws appear with my BK2 in a recent post). I cut through the jaws with relative ease... it was a bit like cutting through a hard, dead branch of wood. However there were a few small 'dings' in the blade when I'd finished. This isn't a big problem on a $15 machete, and the blade is sharp enough again after a rudimentary sharpening. I believe that jaw bones are more dense than the vertebra bones, and when I sharpen a knife, I tend to favour a sharper angle rather than a 'strong' one...so I was surprised at how little edge deformation there was.

Has anyone else had any experience with chopping through bones?

Here is a picture I took single-handedly in an attempt to illustrate the batoning method of butchery...

The only time I have gone through bone while butchering was batoning my BK-2 through deer's rib cage to separate it.

Never thought about separating the spine like that.

I have had the best luck using a small bow saw designed to process game. I know its off topic but it is the best solution I have found.
 
I use a Wyoming Saw with a meat/bone saw blade to saw through bone when processing deer and wild hogs.

Some people at my hunt club use a saws-all that is battery operated to speed things up (at a campsite, not out in the woods where the animal was killed).

I use the tip of my boning knife to pop the cartilage that holds the ball and socket joints together, to separate leg bones from the pelvis.

Sorry I got off topic, but I do know some people that use a Estwing Sportsman Hatchet to split the spine and pelvis on game animals; that's sort of like batoning.

Thanks for the comments. No need to worry about being off-topic. To me any discussion about blades of any sort, the outdoors and hunting are all right on topic (but of course I'm not a moderator). In fact, any respectful comment on any topic made by someone who hangs out here is welcome. It is great to learn what other people do on other parts of the planet. This is a good forum contributed to by some nice, interesting helpful folks.
 
The cordless Sawz-all is great for in the field cutting or in camp.
I've seen photos of old splitters - long two handed handles on a fairly long blade .But I'm not sure what they are used on. I'm sure they would do a sheep or goat by an experienced man ,in one swing. Beef would take a few swings.
BTW the bones of a just butchered animal are less brittle than an old dry bone.
The trick to chopping bone is to not be timid ! Whack it !! A good heavy duty chopping block is best ,like butchers always had. If the carcass or block move that will absorb energy instead of cutting. More blows , more chips.Weight counts .My commercial chopper has a 8.5"x4"x1/4" blade and about three pounds.
 
Works great.

I've also been happy with game shears for small game. Don't know what took me so long to discover those little buggers. :p
 
I don't see many big chopping blocks nowadays. I guess butchery shops may have one 'out the back'. When I was a kid I remember seeing big chopping blocks in the front of the shop where customers were served. They might have had in big hollow in the top surface from many years of use. There was also sawdust spread over the floor, and the place smelled great. Sometimes us kids might be handed a saveloy (cooked sausage) by one of the staff.

I agree that it is best to give bones a hearty whack if you want to cut through them. In my fairly modern house my kitchen bench is so flimsy I dare not do any hard hammering on it. We aren't allowed a woodburner in our area so I don't split wood, but I still have a nice chopping-block out in the garden. It would generally have to be cleaned off before putting meat for human consumption on it, but at least I have one.

Those game shears or heavy kitchen shears are good for small jobs. I sometimes use a pair of old garden secateurs for chopping the claws off possums I'm going to skin so I don't repeatedly puncture and lacerate my hands. Our possums are different to the American version, but I guess all types have claws.

Raccoons have freaking daggers ..lol Sorry off topic, but man I have seen a raccoon cut through heavy denim like it was paper.
 
In regards to the blade damage, teeth/tusks are a lot harder than regular bone.

About your meat handling, it is a great way of butchering. Chris

Thank you for the batoning pic. We butcher deer and sheep, and prefer bone in. I never tried that, but I will now. Usually use a Zaw saw but the bone powder is a pain to remove or wash our. I love the cleanness of your cut.

I've never had to break down an animal in the field but cutting through bones at home, I've used a heavy carbon steel clever with a coarse stone or aggressive steel hone to bring the edge back a few times. For thicker stuff like leg bones I use a pipe saw.

If fragments and dust are an issue, from chopping/sawing, why not just wash the meat thoroughly? Unless of course you are also cooking and eating in the field. Which case a body of water may be hard to find in immediate vicinity.
 
I have occasionally washed meat to remove spattered gut contents or whatever, but I've come to appreciate strong paper towels. I can use them dry, or maybe dampen them with clean water. One of the things I haven't yet mastered is keeping possum fur off the meat. The danged stuff goes everywhere.

Another thing I do nowadays is keep a spray bottle filled with white vinegar in the kitchen. After I've cut up the meat or fish and have got rid of all the junk off the bench, I like to give the surfaces a spray of vinegar and then wipe everything off with a couple of paper towels. I wouldn't claim that vinegar was the world's best antiseptic, but I'm sure that the acidity deters bug growth... and it makes a good job of cleaning, and preventing potential odours that might make me unpopular.
