A honing tool for sharpening an end of an electrode to be employed in the fusion splicing of optical fibres includes a rotatably mounted honing wheel of frusto-conical shape and a rotatably mounted bush whose axis is parallel to that of the honing wheel and is so coupled to the honing wheel that, when the honing wheel is rotated with respect to the body of the tool, the bush will be rotatably driven in the same rotational direction. An electrode is so mounted coaxially within the bush that an end of the electrode will bear against the frusto-conical surface of the honing wheel and that, when the honing wheel is rotated, rotation of the electrode with respect to the bush is prohibited and the abrasive frusto-conical surface of the honing wheel will form a sharp point at the end of the electrode. |
