Wick cutter
An idea i have thought of is there is a lot of coil making jigs but no one has thought of a wick cutter just like a small guilotine were you put your cotton pad on to and has a markings on it to cut your wicks for example you havve 4 ruler markings one for a 2mm coil and so on up to 4mm so you cut the perfect wick all the time and fits the coil perfect meaning more vaping and less cotton wastage and would be perfect for beginners as well as the advanced vaper.
