The same year was also introduced a warranty for life called ''[[Gold Seal]]'', recognizable by the mark shown in the figure, as a response to the [[Sheaffer]] ''[[White dot]]''. The ''[[Gold Seal]]'' remained in use, with some variation in size, on every model produced by [[Eversharp|Wahl Eversharp]] until the [[Skyline]]. The mark is made by two check signs to form a "W" that remind the name of the company. It happens sometimes to find pens in which the ''Gold Seal'' presents a hole, this is not considered a flaw because it was the company that carried out the drilling to mark the lack of guarantee for the models put into liquidation.
