There is not much information on the Brother KL117 knit leader but it is very similar to the Brother KL116 charting device (so read my article on KL116). The minor difference I identified so far is the color scheme (I’ve seen two different color combos – white/grey and white/light-orange).
Judging by the Japanese writing even on the mylar sheet, Brother KL117 was very likely released to the Japanese markets only.
