Here is an easy and quick way to cut paracord; use a woodburning tool with chisel burning bit.
Step 1: Cut Paracord With Hot Woodburning Tool
Just measure your length and use the woodburning tool and quickly and easily cut the paracord. You don't need a knife, a lighter or an open flame. You can pick up a woodburning tool on ebay for 9.00 to 20.00 dollars.
I make paracord bracelets and even cut and burn the finished ends with woodburning tool.
