The Core of the Build: The Wa-Handle
Japanese knife handles are designed to be a temporary, replaceable part of the tool. Because of this, many blades come with mass-produced handles that have sloppy geometry or feel overly bulky. This creates a disconnect between you and the blade, reducing the accuracy of your cuts. I spent years measuring high-end samples and testing prototypes in professional kitchens to establish exactly what works and why.
My wa-handle dimensions and methods focus on a high-performance octagonal shape. This gives your fingers constant feedback on the exact angle of your blade. I use a specific front-to-back taper that locks your hand in place. This prevents your hand from creeping forward, or feeling like the knife will slip out of your grip.
In the Wa-Handle Guide, I also cover specific shaping methods to improve comfort as well as blade-mounting measurements for a secure grip, no matter how you hold your knife. These are the proven blueprints I wish I had when I first started customizing Japanese knives.

Get The Handle Making Guide!
When I was considering trying to make my own handles, a renowned, professional handle maker recommended I buy Colton’s how-to guide. It was great advice, he was absolutely right, and I recommend it to everyone! Yes, Colton details how to do the entire process by hand but the information is completely applicable no matter how you want to approach it!
I have all the dimension pages printed out and posted at my work bench now.
If you’re thinking about making your own Japanese wa handles, I can’t recommend this guide enough.
Traditional Methods Made Very Simple.
I learned everything I needed to know about working with wood and knives from Colton. His methods are easy to follow, intuitive, and best of all traditional. Even now with lots of experience myself and a successful small knife business I still refer to his expertise to refresh my knowledge and solve problems.
Highly recommend to anyone looking to feel more connected to their knives and explore a very rewarding Japanese craft.
Great Guide On How To Make Wa Handles.
This is a very well written and thought out guide to making handles. From tool selection to understanding grain direction this book covers all you need to know to get started making handles. Not only does he list the tools needed but also why he may have a preference for a specific style of tool, this also applies for the methods he uses for constructing handles. I think the information in this could be useful for anyone ranging from novice woodworkers who may have little or no experience to those who already have woodworking knowledge and would like to have a better understanding of Wa handles.
