In addition to the instructions on making the knife I will include an explanation on how I replicate the knife design. (I ended up making 4 of the same ones)
These steps are not exhaustive and assume the maker has experience with some basic metal working tools.
-Angle Grinder (with different grit flap disks)
-Lawn Mower Blade
Step 1: Safety
In this case it would include:
Respirator (remember grinding disks are putting many nasty things in the air)
Gloves (although not necessary and not for use when working at a forge I like to use a good pair of leather gloves to lessen the vibrations when I am working with grinders.)
