You can do this too….

Yep. That's another version of accordion cutting that works well. Thanks for adding that.

The only bad experience is the one from which you learn nothing.

Cleaning out old photos from computer and stumbled on this. Thought it would fit here. I made the steel and a friend, John Young made the knife. Don't remember who the note was for or why it was photographed. I probably learned this from Ron Claiborne.

Nice addition to the thread! Very nice pattern and a fine job on the finished knife too.

A quick example of cutting grooves for ladder pattern. This pattern looks best in the 250-400 layer range. These bars were 300+ layers and I drew them out to about 3/8" thick, or a little less.

The grooves are laid out on each side so they are offset (mostly)

Here is a very short video of cutting the grooves with a 3/8" carbide burr in a rotary tool.

From here you can either forge the bar down flat and stock remove everything you don't want, or you can forge the blade to shape.

I choose the second option and start by cutting a small piece off the tip at and angle and work the point and bevels.

This starts the back-bend of the blade spine, so I flatten out the spine area and stretch the blade.

When you have the blade shape you want, work the tang.

 I did 5 blades from these two bars, and a sixth one from another bar.

This just in. A very nicely written introduction to pattern welding by @Matt Walker
