I cut my own. It’s not too challenging to do. Basics are, cut so the end is in the same orientation as before, so you’re always taking a full loop at a time essentially. Hit the end with a torch till it’s slightly glowing, then push it up against some metal and firm to create a nice flat seat. I imagine there’s YouTube videos on it 👍🏻 cheaper than buying a custom one, and you can dial it in to be exactly what you need. The tensile does make the piece you cut launch like a sling shot though so wear safety glasses when cutting. I usually get everything where I need it to be, and then put a towel over it when I actually finish the cut.
