I have three Muhle STF brushes from AP Shave Co. None have shed. In addition, I have a G5, G5c and a Synbad from AP. No problems with shedding.
Just luck of the draw, i guess.

Wow, very interesting that you had the same experience and also from AP Shave Co. Crazy to me because I thought he gets them from Muhle directly, I wonder if it was just a bad batch and I got my two from the same batch that you had?I have documented in this thread in the past, Sept 23-Jan24, I had an AP ShaveCo / Shavemac Beehive w/ STF XL that had shed since the day I bought it and after a couple months I finally bit the bullet and did some experimentation on it to see if I could figure it out...
I then bought just the knot from @Rudy Vey and installed it in a Chisel & Hound handle I had purchased and not a problem with it since putting it into use this past February. I couldn't tell you why but even in use I could tell they were very different knots but to this day the C&H STF XL hasn't shed anything that I can remember.![]()
Yes, I mean, I am still new to wet shaving (about 7 months in now). But I just face lathered the same as with all of my other badgers and synthetics so I wouldn't think it could be user error. Have to think it is a bad batch, not unlike me at all to purchase two knots from the only bad batch of Muhle STF XLs ever though, that is very par for the course for my timing in life hahaHis first knot sheds too, less but it sheds. If it is not user error, it may be a bad batch.
Which handles do you set STF XL into? Is there anything to keep in mind when shopping for handles that we intend to use with STF XL, obviously other than that it should be 25-26mm in diameter?I've bought 3 STF XL knots, all were from The Razor Company. The two I set in handles haven't shed at all. The 3rd I'm holding for the future.
Bigger isn’t always better, but in this case, it’s true. I’ve heard the XL is the best of the STF lineupPerhaps I should add the XL size to my collection! S-sized STF classic and M-sized Jack Black STF below.View attachment 1935031
It's a fine brush. I want one with the newer fiber, as I heard it splays slightly easier.View attachment 1935521
A few days ago I never would have thought I would need to buy another brush for the rest of my life. Then I had to read all 19 pages of this thread and immediately bought myself one to try.
I have the new dense++ version; it splays marginally easier than the older STF, but both walk the easy side of the street. I have yet to read a review of the new fiber without the extra density.It's a fine brush. I want one with the newer fiber, as I heard it splays slightly easier.
The new dense++ definitely seems to be the more popular option. All the brushes with that knot and knot itself are sold outI have the new dense++ version; it splays marginally easier than the older STF, but both walk the easy side of the street.

The extra dense new version splays marginally better than the old extra dense, or the old regular density?I have the new dense++ version; it splays marginally easier than the older STF, but both walk the easy side of the street. I have yet to read a review of the new fiber without the extra density.
