A new utensil which solves the aforementioned problems due to developing an instrument with a number of advantages compared with the traditional method already described for lubrication of fishing lines and leaders. This tool fundamentally helps this operation to be made comfortably, fast, in such a way the user can hold the rod while proceeding to the greasing and the guiding, for the storage of the assembly into the reel, is done through this, so the risk of the lubricant not remaining finally on the fishing line and/or leader is diminished. It is basically made up by two parts, on the one side, an outer cover which enables its fixing to the rod through the upper hole, also houses the support material for the lubricant and contains a cavity that allows the storage of other instruments, as well as the tool for the impregnation of the support material with the lubricant.
