Buy just what you need
Big cutting board
8 inch boning knife
10 inch breaking knife
Hand meat bone saw
Grinder
40 lbs hogs do well whole on a pit just saying
yup , only thing I add to that list is a Diamond steel , but if you have another fast easy way to touch up your edge you are good I like the Dexter 12 inch
https://www.amazon.com/Dexter-Russell-DDS-12PCP-Diamond-Sharpener-SILVER/dp/B081SSFYQPI like a 5 or 6 inch boning knife myself
and an old hickory 7-7 butcher knife
and a cutting board you could break those hogs down just fine add a gambrel and you can do the big ones fine also
if you have a clean hack saw frame and blade they actually work quite well or buy a meat saw , meat saw are easier to get clean.
you also don't need a grinder it is a time saver , but you could cube the meat also
it comes down to most people make way to much of the tools
a well prepared kitchen really only needs 3 knives , an 8 inch chefs knife , a parring knife and a serrated bread knife.
to butcher a skinning knife , a boning knife and a butcher/ breaking knife and you are good to get meat on the table
I use the cheap plastic ikea cutting boards I have had big boards and found them a pain to clean the 14 x18 boards fit in my dishwasher a cutting board only has 2 duties , protect the knife/counter and come clean easily. you could make a wood one if you can wash it clean.
I like meat lugs because they have lids and I can stack them in my fridge but I worked with big bowls for a bunch of years
I have the 3/4 hp LEM big bite grinder it makes short work out of 50-60 pounds of ground
the amount of meat you get off a little 40 pound hog you be lucky to get 15 pounds of meat , you might as well make them 1/4s and put them all in a nesco roaster and make BBQ out of the whole pig you only need a knife or two for that
