My first project was made from a piece of bamboo countertop material my daughter sent me. She got it as a sample when she was considering replacing her kitchen countertops. Ultimately she decided to go with a different material, so I got the sample to work on. Below are 2 photos showing the entire piece and a close-up of one edge.
As you can see by comparing these photos with the others of the stock I purchased, this material is clearly different. It is comprised 5 separate layers of long bamboo strips so it yields a significantly different look when turned into a finished piece. So far I have not found a place that sells this type of countertop material but I expect some further investigation will turn some up.
