Cordage Making Tool Expansion and Reducer Kit.

The Cordage Tool Expansion and Reducer Kit allows you to cut materials twice as thick as the standard thickness, or as thin as about 1mm (which makes great fishing line).

So when you combine this with the current spacers this allows you to cut Large, Medium, Small, and extra small cordage. 

this expansion set works for all three types of cordage makers (card, dog tag, and micro)

Be aware, the smallest setting is the most difficult to use as it can easily slip off the bottle, however with practice you can get around 275' of fishing line thin cordage from a single two liter bottle on the smallest setting!
