I've sorted quite a few deer in my job
I've never needed to use anything bigger than a four inch knife and a saw.
I've seen a professional stalker take a warm Roe buck, gralloch, skin, joint (including removing the head) and even remove the mask ready for the head to be mounted using only a four inch blade. Possible if you cut in the right places. I'm not that skillful so I resort to a saw aswell
It's a sound plan to treat it like a big rabbit. If you're looking to eat the beast yourself it doesn't matter how you cut it up as long as it suits you.
This is how I normally do it...
I normally hang it for 10 days in the winter (less in the summer), I've just finished dealing with two I shot after Christmas. I slotted a metal bar through the hocks and suspended them inbetween two shelving units in my garage. Extremly heavy to lift both at the same time :roll:
Take it down when you're ready to start, skin the back legs while on the floor. then when they're clear lift it back up and suspend it as before, you can now work on the carcass without needing to move it again.
Remove the rest of the skin moving downwards, then start jointing from the lowest part (front legs) moving upwards. By the end you should have two rear legs swinging from the bar/ hooks or whatever you've used to suspend it from.
Hope this helps
