Fishing Knots: by Seaguar

This is really a gold mine. Japanese brand Seaguar has a very well made special page on fishing knots. You basically can see them all in a single page with drawings and videos. I think is the best page I have seen so far when it comes to fishing knots. Knots like Albright, FG, PR, clinch are all here. Just use google translate and you will be fine.

This is the albright knot page.

Tony Pena Knot

This is a great knot for PE to Leader connections. It is not difficult to make and this video explains it well.

Knots...Knots...Knots

You can have the best lures, reel, rods, clips, hooks but if you mess with the knot you may end up losing the fish of your life. This sentence is pretty much cliche but it is true.
I don't like knots, I always try to tie the best knot and lose time but it is essential when you fish.
There is one site that I actually enjoy checking from time to time. It is Animated Knots by Grog. It is a wonderful site with a great archive of knots. You can find anything from climbing to fishing. Every knot comes with animation video and step by step pictures. I would definitely recommend it.
By the way, my favorite knots are the palomar, albright, improved clinch, tony pena knot and perfection loop. I need to learn the bimini twist though.
Enjoy.
