I have had makers tell me they have a harder time making shadow pattern because you have to make the bushings for the outside of the knife handles.
A great point, Rick. I've had two makers turn down a shadow order for that very reason and had others "acquire" their bushings from other sources.
I went to not using bushings for micarta and G10 since it isn't really necessary for those materials. I performed a destruction test to make sure too. http://knives.mutantdiscovery.com/destruction.html
Since then I found out a neat way to make the bushings. It works really well. http://hackaday.com/2010/02/26/drilling-perfectly-centered-holes/ Nobody has an excuse anymore after reading that article.
