sakimoto, You sure have the ambitions part down.
Most of my work is done with old files and the older and rustier the better they are steel wise.
7X57chilmau has given you some very good info too. The thing about knife makers is probably no 2 men make and or use the same tooling. So everyone of them has their own ways.
It is a rare man who can hammer to a finished blade too.
So I use both a coal fired forge I try to burn charcoal in because I hate the sulfer stink 'coking' coal makes before the stink goes and you have a 'clean' fire.
Lets talk tooling because you need more. I suspect you will have many of what I list right now.
Keep an eye out for a real anvil, but you can use rail road track, and you can even have a section of some milled flat for not that much money. If I were going to do that I might select either a piece 12 inches long milled flat, and or combine about that much leaving the curved part alone.
Many shapes will have many uses, so that curved part will have it uses.
Collect old tools at yard sales.. This can be a cheaper way to come by odd tools that will lend to many things making a knives.
Get a bigger grinder than what you have when it comes to you. 8 inch or better is good.
Other heat sources are good too, like a old beat up wood stove that can sit in the weather and some fuel for it. This stove may need apx 6 feet of smoke stack to get a draft, and by leaving ashes in it, and sand if no ashes are available at first you have a tool that can anneal steels, or normalize them.
It can be the source of heat to harden and then temper too, the hardening being the easier of the two heatings than the tempering would be.
A 2x4 like size block of steel apx 12 inches long, or a section of railroad track you can place in the fire for tempering would be handy as well. This might be best with a ring about 4 inches across, so with a look made of a steel rod you can snag the hot block from the fire, and drop it in sand screamin hot.
Welders gloves are not very expensive. These are the very same things sold for wood stoves for much more money. Welders use these and burn them up faster, so that is where to buy these gloves.
A clear face shield to protect your eyes is a must have item, and when you are grinding you should be wearing it NOW. You loose your eyes and yer all done!
Hammers , pliers and when your ready tongs... A bucket of water.
Power drills and bits. Wire wheels mounted on a motor, able to take other wheels made of stone, and or rubberized abrasives.
Save plastic caps is assorted sizes, and these will prevent marring fancy wooden or antler grips when you drill holes in them and or soft metals as bolsters.
Wire cutters that are strong enough to cut a 8 penny common nail, or brazing rod, which I use as pins.
Wooden blocks to be made into custom forms and use with sand papers. A good hard glossey paper magazine wrapped in tape to become a round sand paper form.
A few cakes of bee's wax, boiled and un-boiled linseed oil. Masking tape.
A metal box made like old window boxes were once made for a quench tank.
It should be no less than 6 inches wide 8 inches deep in oil level, and about 2 feet long, and have a wooden cover, or a metal cover, to pul out any flame up and or to keep weather out of. (The last thing you want in the oil is water on the bottom.)
Never ever quench any tool steel to harden in water! If you do, there is a good chance you will crack the piece you just worked so hard to shape.
Water is for working a hardened piece as you work it, and not for much more. And or chilling a piece that is already soft.
Even with a oil quench you can expect to crack an occasional piece.. It just happens.
A magnet from some old speaker, and a small chain to hang it, mounted in such a way that you can dangle the magnet on a bright red hot blade in day light.
As many good working files as you can get and in every shape known to man in time. No less than a flat file, a round file and a 3 corner file. In time finer cuts of all of these as well.
The oil I try to get for quench baths is used canola oil from a restaurant. This smells more pleasing and may make you hungery. It has a higher flash point, so is less likey to flash when you quench.
A metal trash can with a lid for oily rags or you will get a fire from the rags called spontainous combustion when you are not looking for any fire!
Any kind of blower. Mine is a old rivet forge blower I can run by hand, but any motor you can run with a squirrel cage blower will work. You might want a varraible speed switch in line so you can controll the air blast..
That with a pile if sand and some fire bricks will make about any forge you want.
With the above and a wooden tray you can make a forge that will not soon burn up the wooden tray, odd as it seems.
A vise and the bigger a vise the better, and a way to mount it so it is stable.
Various padded jaws to fit that vise, as hard studded vise jaws are a tad too much for certain items. Alumium angle stock is one way, as is copper plates made of roofing copper mounted on wooden blocks can be another way, as well as wooden blocks coated with thicker leather. It all depends on what you are going to hold.
The only best thing about store bought is it come faster, so long as you have a bucket of money, and I don't.
I can take a old file and make a blade of it that will cut, hack and slash another old same file that has been annealed.
I may have skipt over some tooling as all of this is coming off the top of my head.. so sorry, and like I said there are no 2 men who work the same way.
All but one are old files here, and the one that isn't is a old power hacksaw.
Probably the next post will be more on How To my way... and stock to get.
