With my screwdriver.

Unless you're a blacksmith who makes his own drivers or a wordworker who makes her own handles, the same is true for you.

I have a custom wrench in my toolbox. I forget what the issue was, but 15 years ago I think I was working on someones skis or something? Anyway, I had to cut the handle in half and welded it back together at a different angle.

Quick and easy hack job. I'm not a machinist, mechanic, or metal working professional of any sort. But I had access to a shop at the time, so I was able to take my tools that were almost what I needed and turned them into exactly what I needed.

Literally no biggie. I feel like I'm hanging out in the kind of crowd that unironically asks "why do you change your oil yourself?"
