Hooo-Boy! That quest is being debated to some degree as we read this, right here on our fine forum, in more than one thread.
I would recommend beginning with sandpaper. Get automotive (body-shop) sandpaper. You can get three or four grits at a time this way, usually right down to 1000 grit, starting with around 80 or 100 or even 120. Let's say you get four packs. One each, at 80, 180, 320 and then 1000. These are not necessarily exacts, but you get the idea of graduating (stepping "up") grits in sequence. This is the whole idea. Start rough, and get smoother as you go. Cut the 9" by 11" inch sheets in half lengthwise so you get 4.5" by 11" sheets. Adhere one of these sheets to something smooth and hard like a granite or marble flooring tile or a piece of glass (must be really smooth and flat! -And supported underneath). I use a light coat of spray adhesive.
Flatten the backs of your chisels as best you can with 180, then 320.
Then get a good "idea" of what a 25 degree angle is and with the 80 grit, get a good bevel started at that angle. It doesn't have to be perfectly 25* now because you're just doing this to get the idea of how to sharpen for your needs, and your style here.
Do the same with the following grits, 10 to 20 strokes, whatever feels right. Stop at 320 grit and check your 90 degree angle at the tip for true 90* (perpendicular to the side) angle, and adjust accordingly. Finish off with your 1000 grit at a very slightly higher angle than the 25* on the bevel side, gradually, carefully get a feel for "shaving the skin" off of the surface of the sandpaper. You'll feel it. Just a few strokes. Then flatten the back again using the 1000 grit this time.
You'll be amazed.
Keep something handy for brushing away the fine dust out of your paper between working the chisels.
Mind you, this is just a start. Just a beginning. Just to get you an idea. Do it "dry". No water or oil. No stones. All that will come later. Trust me on that.
Good luck and don't cut yourself. Please.
p.s. Those Marples' should do you just fine.
