Rope Cutting Heated Blade

I got tired of having to cut a piece of rope then using a lighter to seal the ends. I know that you can buy heated blades but they are about £45-£50. So i decided to make my own, i picked up a fairly cheep soldering iron and replacement head for £1 at a local hardware shop. Using a large hammer strike the soldering tip repeatedly from both sides until it is flat. It looks more like a screwdriver head but it does the job. To use it simply plug it in and wait for it to heat up, then apply to the rope and press down hard, it will cut it using the heat and seal the ends at the same time. You don't need a sharp edge on the solder tip for this to work.
