Of course that makes sense. As already mentioned above, how about cutting off the extra metal?Not really. The metal ring is a good 4 mm wider than the "hair" is, so one would need a hole of 26.4 mm to get the metal inside. The knot size is only 22 mm. I doubt one would get the effect one expects when setting the knot deeper - a less floppy, moppy brush and more backbone with much less splay.
