Clove hitch virtually every time I'm out. Ditto with square and diagonal lashings.
Sheet bend, probably tie this a couple of hundred times a day, so can do it with my eyes closed no problem.
Fishermans knot-Occasionally.
Reef knot not that often but sometimes.
Round turn and two half hitches often.
Timber hitch occasionally, but not that often.
Prussik loops a few times.
A few fishing knots whos namews I can't remember a lot of the time.
Bowline occasionally, triple bow sometimes as well.
Figure of eight often, and the double as well.
Sheepshank- I like this knot, but don't use it that often.
I'm sure I've forgotten some.
