A method of forming an article on a tool and an article. The abrasive stratum is flexible or deformable, and protrudes from the holder. In certain example embodiments, the substrate may be provided with a conductive layer thereon, and may be electrically biased in the deposition chamber. The top face of each middle block has a substantially pentagonal shape having five sides which are an axially inner side extending in the tire circumferential direction, a pair of transverse sides inclined so that the circumferential distance therebetween is gradually increased, and a pair of axially outer sides inclined so that the circumferential distance therebetween is gradually decreased. A selection of one of the available voicemails is received. According to the invention, fixation means which define a rotational position of the restoring spring relative to the tappet are disposed on the contact face of the tappet.
