The “tweak”: I read it on the forums, I don’t remember which one. People realized they could use shims to make the razor more aggressive, and not long after someone found out you can loosen the handle without negatively affecting how the razor handles. And no, it doesn’t really clog, it usually gets the area I’m targeting with one stroke (YMMV as they say tho). And it flushes out really well, too. Nothing in there when I disassemble to let it try.
