Writing with a pencil produces a very particular sensation, which is partly governed by the softness of the pencil lead chosen. This pencil lead holder is, in effect, a special form of pencil with the advantage that it can be “refilled” again and again. The Penxo gives this writing tool a fascinating new twist. It succeeds in combining a form reduced to the essentials with an innovative construction. The strict minimalist approach does away with the usual assembled components. Instead, the casing of the Penxo is carefully made from a single aluminium block. As there are no springs, buttons and other mechanical parts, this pencil lead holder with a diameter of just 2 mm looks seamless and cohesive. It is simple yet stylish and stands out due to its carefully considered functionality. A slot in the centre serves to release the lead and also as a window to show the colour, marking and usage level of the lead. The slit at the tip of the pencil creates torque at the other end so that the resulting counter-balance exerts a clamp-like hold on the pencil lead. This astonishingly simple, but sophisticated functionality makes the Penxo pencil lead holder an impressive tool for everyday use and provides a successful, contemporary reinterpretation of the humble pencil.
