This is what I've started to do as well. Very frustrating. The Kodak black & white film I've processed recently doesn't exhibit the 'filament' issue.

I processed three rolls of FP4 at the end of last week, and all three had filaments coming from the edge of the rolls.
I've gotten into a habit now if running my wet thumb and forefinger down each edge, one edge at a time as the roll comes out of the photo-flo.

- this does seem to work however I missed one on the HP5 films mentioned as being processed most recently. 4 rolls of slightly older Delta 100 - dated July 2021 - do not seem to show the filament from initial assessment.Have you seen a repeat of the filaments since you started running your HP5/FP4 film through your fingers?
I've asked Harman/Ilford to check....no response yet.It may be something as simple as a problem with the cutter that trims the substrate stock to the correct width.
Has anyone checked to see if the blade needs sharpening?
And how could produce pulling film from the reel produce filaments. more so of that tinyness and regular dimension?
I have always pulled film from a closed reel and have done so for 15 years since I started to do my own developing. In fact to be honest until I read the posts about pulling from a closed reel I had never given it any thought as a potential problem. While Jobo reels can be opened there are reels that cannot be opened such as Durst where you have no choice but to pull the film from these closed reels. Never had a problem with Durst reels eitherI also never pulled off film from a closed reel.
But I know quite some people do, and we did not learn of these filaments before. And how could produce pulling film from the reel produce filaments. more so of that tinyness and regular dimension?
Oh yes, they do look like scratches to me. You also have several on the right side of the negative. These look like handling issues; practice a little more with handling your film sheets.I suppose that gives cause to scratches but marks don't seem that.
Looks like scratches that form from sliding the film around with some bit of grit under it. I filter dev and fixer through a fine mesh before pouring into the tank - I would be especially careful to do that if I was reusing developer. One thing about scratches and scanning, though - often, scratches that stick out in a scan don't show up in an enlargement (or show up less significantly). And, then, you can always rub a bit of nose grease to lessen it.

Btw you also managed to scrape off some emulsion in the top right corner; seems like a handling issue when the film was wet. The white "filaments" are handling issues with dry film before development.
Don and Koraks thank you both. Man sounds like I'm a f'ing gorilla in my handling of the film! Embarrassed as I've been thinking I'm careful! Anyhow need to improve there. I'm loading the holders in a changing bag and perhaps I'm rushing there at least with this one. Not all I've done so far have had flaws but I was a mess on this one as from what you are both saying, it's sounding to me like at least the scratches occurred in the load stage (pre-exposure) particularly if the upper right corner marks are removed emulsion which I kind of thought same thing and that could be sweating hands or the lack. Anyhow I appreciate both your inputs. Jim
Very much agree! For me it made a world of difference to have a room that I could darken completely. It's so much easier that way. A changing bag was always sweaty hands and not enough space especially for sheet film.I think a change bag will easily enable film to be damaged.
