There has been recent post about axe collars and this may have been posted before. I am an elementary leather worker at best and I have found a cord whip to be a very effective, simple and economical way to provide a little protection for a haft. I will add that I find it more ornamental than practical. I would suggest that you google (or however you search) whip knot, whips, knots, or whatever it takes for you to get a better tutorial. This is just how I do it. Shout out to @andy.t for the really nice bank line. I ordered this for this purpose. I start with cord, tape, and an axe with the edge protected. Next I tape a loop along the top of the haft. Now starts the fun. Begin to wrap the cord around the haft and the loop towards the top. It is not hard but you need to wrap it as tight as you can. Keep wrapping it towards the head. Keep the loop laid down. Stretch the loop as you go to make sure you don't lose it at the top. You have to have enough at the end to run your cord through to lock it down. Now your getting to the important part. You have to wrap on to the head and run your cord through your loop. Like so. Snug the cord and then pull the other free end with pillars to lock the knot. If you wrapped it good and tight you will need pillar to pull it. The upper part of the loop should look like this. Once you do it a time or two it is a very easy. It is not easy on the hands. I've not had one fall apart if tied correctly. Very durable. Not bad looking either.
