Great knot with just the right amount of backbone and scrub. Initially, the knot might feel a little scratchy, however after 2 or 3 shaves it softens up nicely as the boar hairs begin to split at the tips. While this knot is 26mm, it has a massive bloom.
It's also worth noting that the base of the knot plug measures 26mm, but I measured nearly 28mm at the thickest part of the glue bump. I wasn't able to get this into a 27mm socket handle, though I'm sure there is some variance in these knots. I would shoot for a 28-30mm socket just to be on the safe side. Other than the wider than expected glue bump, the knot performs much better than the price would lead you to believe.
This is easily one of the better natural fiber knot options under $30, though Maggard's two-band badger knots are phenomenal in the same price range as well. If you like backbone with a little more scrub, this is the knot for you. If you like backbone and soft tips, check out Maggard's two-band knots. Both are great and won't break the bank.
