Here are some photos from my work. This was a unusual request for my shop since we never have worked on knives before, generally we make tooling for other manufactures.
A walk-in customer asked to have a logo put on their kitchen knife and it was too intricate to mill so we decided to "burn" it into the blade using an EDM. Needless to say this was a fun job for me to do. Wish I could afford to EDM the blades I make!
The first picture is of my setup, I had to protect the bone handle from the EDM fluid with a plastic bag and some tape
Here is the logo actually being burned into the blade. The black square thing is graphite, the graphite is machined into the shape of the logo and then the logo is burned into the blade, in this case with about 10amps of electricity.
Thanks for looking
