A craft needle having a measuring scale permanently applied along the longitudinal surface is disclosed. The upper metal line includes a diffusion barrier, which is made of a stack of a first WNx layer, a WCyNx layer and a second WNx layer. The method can include placing marking material on the photoreceptor using the developer. Added functionality can be gained by co-forming the porous material with non-porous material to create an article with layers of differing characteristics. This configuration makes it possible to align multiple pieces of information relating to motion in a good balance as a whole, without disturbing their original waveforms. The external adjustment device further includes a motor mounted inside the first handle and a first button located in the proximity to one of the first handle or the second handle, the first button configured to be operated by the thumb of a hand that grips the one of the first handle or second handle.
