I am a person that like all wood with 7 plys very much =) i have tried some 7-plys of wood blades, and all of them have three same thickness plys at mid, difference from allmost 5-plys of wood and carbon blades. I have seen a few 7-plys of wood blade with 1 thick core and 6 thin plys for 2 sides. But i have't try them. Do you know the different feeling about them? And why we dont have many 5-ply blade with 3 same thickness core, or alc and zlc blade with 3 same thickness cores? Tks!
