Single Point Square Top Needles come in diameter ranges of 4mm to 25mm and the finer diameters make a closer knit, while the larger ones give a larger knit. These Needles are suitable for flat knits and with a square block at one end, these are used specifically for flat knitting as well as hand knitting. The Square Top Needles are offered in a length varying from 7.5 to 14 inches. Single Point Square Top Needles are provided in hot stamping in both US and metric sizes that give them a unique appearance.
