Pyramid Honing: A Photo Tutorial
Few topics generate more questions from newbies than the cryptic-sounding "pyramid method" of honing. There are some good threads out there that explain it, but I thought a photo tutorial might help fill in a few gaps. Before I get started, I want to thank Jim at Vintage Blades for his patience. When I originally decided to write this tutorial several months ago, I didn't have a Norton combo hone to work with. Jim lent me one, and waited, and waited, and waited... Finally I decided to just buy it to make the guilt go away. :) Thanks, Jim.
Enough of that...
What is the pyramid method of honing?
The theory behind the pyramid system is simple: You alternate between hones of two different grits, using a lot of strokes on the coarser side to start out, then using fewer and fewer as you continue. Usually, the pyramid is done on a Norton 4000/8000 grit combination stone, which was popularized by Lynn Abrams, SRP's founder.
It's called a "pyramid" because the strokes on the coarse side of the stone taper off as you go: You might start with 10, for example, then 5, then 3, then 1.
The pyramid is a popular approach because it's simple and it works. As you progress in your honing abilities, you'll develop theories as to why it works, but even some of the more advanced honers seem to disagree on the theory behind it. For right now, let's just say that it helps you avoid some of the vexing problems of honing and creates a clear path for you to follow. It helps you avoid the dreaded "overhoned edge," and it partially answers the question "how many strokes do I do?"
You'll frequently hear two different pyramids mentioned, the "conservative pyramid" and the "aggresive pyramid." Here's how the conservative pyramid works:
1 stroke 4K, 5 strokes 8K
3 strokes 4K, 5 strokes 8K
5 strokes 4K, 5 strokes 8K
3 strokes 4K, 5 strokes 8K
1 stroke 4K, 5 strokes 8K
See how the number of strokes on the 4K side of the hone increase and then decrease? There's your "pyramid."
