The all new Key of Z "Gator Washboard" is made of 24 gauge stainless steel.This is a great unique gift as well a piece of art work and musical washboard. These are one of a kind washboards created by Tee Don. I believe there is room for anyone and everyone to create their own art, and let the world speak to their quality. The most important opinion is YOURS! I let the thousands of musicians around the world, playing my rubboards, speak for the quality, craftsmanship and value of my creations. And, I let my rubboards speak for themselves.There are many rubboard makers. There is only one Key of Z, often imitated. I worked very hard for many years to earn your respect, and honor my Fathers legacy. When you invest in a rubboard, please consider enjoying a piece of history, a Key of Z Rubboard, and share my family tradition with yours. Key of Z Rubboards, played and honored worldwide, for a reason. Id be honored if you play one, too! Merci beaucoup! Tee Don Landry." I am proud to be a positive role model for other Rubboard makers. They copy my designs and products, but not the magic nor the history I handcraft into each board. Come get a piece of Louisiana Music History - Original boards by Key of Z Rubboards!".My Rubboards are finished the old fashioned way,the way we have been doing it since 1946 by rubbing the edges with a finishing stone. Then I buff out the edges with scuffing pads for a nice clean smooth edge.
