Pro tip: I used to hate fitting extractors until I started using a different file
Honestly, for the longest time I always used a standard needle file to fit a new extractor. It was a slow process, and I'd often take off too much material trying to get that perfect hook shape. About six months ago, I picked up a Grobet 4-square file on a whim from a tool supplier in Spokane. Tbh, it changed the whole job. The square cross-section lets you work the inside corner of the extractor hook way more precisely. I can now get a clean, sharp engagement surface in about half the time, and I haven't had a single one come back with extraction issues since I switched. It's one of those small tool changes that just makes the work flow better. Has anyone else found a specific file or method that made a tedious fitting job way easier?

Actually, Grobet files are pretty easy to find online now. A few industrial suppliers carry them without needing a catalog. The square file idea is a solid one though.

Yeah I actually snagged a Grobet needle file set off McMaster last month without any hassle. Took like three days to show up and they were exactly what I needed for some cleanup work on a little brass project.

Wait, you found a Grobet file in Spokane? That's the real shocker here. Those things are like gold dust outside of a big catalog order.
