Go to your local fishing/sports store and buy some heavy grade trot line. Now lay a strand of the trot line the length you want wrapped on your axe handle and then double it so that you've got a U-shape at one end and the end of the trot line and the roll of trot line at the other end. It's best to put the U-part at the top of the handle near the axe head.
Now on the lower end where you've got the end-of-the-trot-line and the roll-of-trot-line begin wrapping the handle going up toward the U-part near the axe head.
Keep wrapping (make sure it's tight) until you've reached about half-an-inch from the U-loop. Now cut the trot line and slip the remaining piece under the U-loop and let it dangle about four inches.
Now cut the trot-line at the roll-end at the bottom of the handle and leave about five or six inches of trot-line.
So now you've got about four inches of trot line slipped under the U-loop on the top end, and you've got about six inches of trot-line dangling a the bottom end of the handle. NOTE: This bottom end of the trot-line is going under the wrapping all the way to the U-loop and it forms part of the U-loop.
Now get some pliers and pull the bottom six inches (this will take a bit of pulling) until the U-loop starts to disappear under the wrapping. When the U-loop disappears it will also pull the four inches of trot line dangling at the top end under the wrap.
AND NOW you've got a beautifully wrapped handle with no knots, no obtrusive kinks, no need to use glue or epoxy or anything else. You'll have two pieces of trot-line remaining at the top and the bottom. Cut them and burn the two ends down to the handle or wrap. You can...if you want to...put a drop of epoxy at the two burned ends but it's not necessary.
If I knew how to post pictures on this site I'd post some pics showing how this is done because I realize the directions are a bit confusing. Sorry about that.
