brihaji,
I guess the arc or plasma too will give only a rough profile, final finishing will have to be done by hand before putting it through the grinder/sander.
Correct me if I am wrong but the metal working part of knife making some what goes like this,
Knife blank-->Bevel grinding-->Heat Treatment-->Edge Sharpening.
So following the above, the first step i.e. blank making is the easiest for us.
Next up, for the bevel grinding, are there any hand tools that can be used in place of the bench grinder?? I bet if an appropriate jig is fabricated or a even a bench vice is used to hold the knife steady, regular hand held grinders can be used to put the bevel on the knife blank. Though this will take much more time as compared to bench grinder.
Heat Treatment, Edge Sharpening will need some ideas too...
