Here is something easy that will get you started and boost your confidence..
This instructible assumes a working knowledge of pattern welding.
This is a recyclable instructible as well as a knife making tutorial.
4 x Black square section spring washers
2 x Large uncoated brite steel nails
Ferric chloride (or the acid you normally use)
Black tie wire (stainless wire will work too, but costs more).
You will also need to clean the washers to remove the fire scale.
Bind with the tie wire in alternate layers the two brite steel nails, and three black washers.
Keep one washer in reserve, this will be the cutting edge.
The nails are naturally scarfed.
Amalgamate into a single billet.
Heat and twist the billet.
As there is not much material you need to slightly flatten the spirals, and then grind until flat.
Grind the knife into the desired shape.
Sand and polish the blade.
Heat treat, then sand and polish again.
