Well I use a wooden post type, have been training seriously with it for 15 months, I do not have any callouses this is due to me using foam rubber target covered in leather. I have built up to 50 strikes a day of each technique. It does offer all the benefits Traditional- Fist lists and also a devolopment in kime. I have been with my current club for 7 months and at an impact training session a senior black belt said that I can hit the focus pad harder than any of the other black belts.(I am currently a red belt in this style) this is not due to size or strenth but correct technique devoloped through the use of a makiwara post. I think that the makiwara is a vital piece of equipment for the karate-ka. Sadly some dont know what it is anymore let alone use one, Maybe this is due to karate going down the sport road. Those that voted yes on the poll what do you use? regards makiwaraman
