How to tie different knots

Ive been fishing a while, and I use a fishermans knot!! Just take and hold what ever you use with one hand, use two fingers to hold it, and with your other hand twist it about 4-5 rounds, and take the cut end and loop it through the end and pull until it ties like a circle with knots, and it becomes cone shaped!! I use this one when I catch medium to big fish, holds good with 8lb test line! Spider wire works well with this technic!! Hope it helped some??
