NO!
Unless specifically noted, all of my knives are made from hand forged high carbon steel. Lacking the chromium that gives “stainless” steel its name, high carbon steel will rust in the hot, damp environment of the dishwasher. Natural handle materials should likewise never be exposed to these conditions.
On a personal note, I strongly recommend that you avoid putting any of your cooking knives in the dishwasher, whether they were made by me, another custom maker, or by an anonymous factory somewhere. Even with the most durable synthetic materials, the dishwasher is a destructive environment for handles and fasteners, and unless you can completely isolate the blade during the wash cycle, chances are very good that the edge will be rattling around against its neighbors–which will cause it to dull prematurely.
Just hand wash them.
