You don't need the crimp sleves or tools.
I use Malin 7 strand uncoated SS, 20lb test and 0.012" diameter. Simply put the wire through the hook eye (or swivel or whatever) and leave a 4" or so tag line. Clamp a set of forceps to the end of the tag line for weight. Spin the forceps around while holding the hook in one hand and the longer length of wire in the other (tight). Watch your chin.... Trim the tag line tight.
This will make a bunch of tight twists that will not unravel with no bulky crimps.
HTH.... Burt
