1c: Stacked Bamboo handles for a Custom Landing Net

Many of my designs start out as a question.  A rod building friend asked whether I had ever seen a stacked bamboo reel seat.  I hadn't but I went with the idea and came up with a landing net handle that honors the use of bamboo in fly fishing.  I now use the stacked bamboo sometimes as a limited design element or as a full handle. This feature adds $100-200 to the price of a net.  Each layer is fitted and glue individually.  Why?
