(NUR KOPF) RazoRock Mentor Sicherheitsrasierkopf

Picked this up as a backup head and honestly, the aggressive/efficient bite is exactly what I wanted — it mows down a two-day beard in one pass without feeling harsh. At just about an ounce, it's featherlight on the handle, and the M5 threading screwed on perfectly with my existing razor.

The threading is standard M5 x .8 so it screws right onto any of my handles, and at about an ounce it’s light enough that I forget it’s in my travel bag. Shave’s got some bite but it’s smooth if you keep the angle right—exactly what I wanted for a backup.

Picked this up as a spare head and it’s already my daily driver—the M5 threading is smooth and the whole thing weighs barely an ounce, so it feels nimble but still cuts through a three-day beard without pulling.
