Knot tying is something we do often enough to need the skill, but seldom enough to where it's not something we normally feel the need to master. A few times in my life I've been called upon to drive something big, or tow a trailer, or tie a load down in a pickup truck. All of the sudden I need to tie something down and I'm usually guessing until I throw enough random loops to where it feels secure, which has usually been a frustrating experience. So ... I wanted to do a few blog posts about tying knots as I learn to tie them the right way, as well as do my own nerdy interpretation of them. Rope, check. Camera, check. Let's do this.
Half HitchWikipedia Entry
The thing to understand about a half hitch knot is that it's not actually used for anything. It looks useless because it is useless. However, it is used by many other useful knots. This knot is also referred to as an overhand knot. You can pretty much keep stringing half hitches together and the knot will get stronger, as well as harder to untie.
Two Half HitchesWikipedia Entry
Here is where things start to get interesting. Two half hitches together make for a strong knot. It's important to note that the loop will want to close; it's not adjustable. If you want a loop with adjustable tension, then you want a taut line hitch, which will be the next blog post in the series.
Round Turn and Two Half HitchesWikipedia Entry
When you go to secure a knot to a fixed object, add a turn around/through something before doing the two half hitches knot above.
