To answer the original question....if the knife is treated as a knife should be, you will not live long enough to know how well the coccobolo handle will hold up. This can actually be said about a lot of totally natural handle materials that have not been stabilized. Never could understand the actual need for a handle to outlast a blade.
That being said, I do understand why many prefer to use synthetics and stabilized material. It's ok for them, I just prefer not to unless a customer requests such. Just doesn't go with my preferred styling.
