Seems like you can get decent stuff from old furniture, but you have to be very picky in your selection, and even then it involves a good bit of luck. Compared to the amount of work that goes into a nice knife, the handle material is relatively cheap if you use medium grade handle material. Keep in mind that the handle material has the second biggest impact on the aesthetics of your knife, right behind craftsmanship. Well, maybe third if you count overall design separate from craftsmanship. If your cash strapped and it's for a rough service knife of your own, it might be a good choice.
In the end, will you be satisfied with the results, or will you look wistfully at the knife, knowing you could have done better? Or would you feel bad every time you used such a pretty blade for hard tasks? It all comes down to personal taste.
Just my 2 cents. If it's worth even that much.
