We’re not sure that one is “better” than the other. Both have their unique benefits. Since plastic is more malleable, there is the advantage of shaping the handles into more ergonomic designs to ease the burden of fatigue that can possibly lead to carpal tunnel syndrome. Also, plastic doesn’t give splinters the way that wood and bamboo have a tendency to do. On the flip side, with bamboo, there is less of a risk of absorbing BPA or other toxins into your bloodstream, which a continual worry when handling plastic. We do offer an excellent bamboo product that has been treated and combines the traditional style handle with a safe, soft, gum-friendly silicone bowl.
