Guitar top nut file tool set Stainless steel Welding Torch Cutting Torch Clean Designed for clearing welding nozzles but is perfect for top nuts as well. A great little tool for filiing and cutting top nuts so that your strings sit perfectly with the action as low as you wish and a price that is so cheap every guitarist can afford to buy one now. Please note this is an upgraded version of the original file where the wire files are now 100mm long with heavier 30mm long cutting file "teeth" The circular files fold out from the aluminium casing and include all the following sizes so even if you have a guitar with hefty strings tuned down to Low C this file will cut the string groove for it. 12 round files in the set in the following approximate sizes. NOTE - this is only suitable for plastic top nuts. This is NOT a professional grade tool, its a cheap and cheerful way to achieve the job. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
