I’m a big fan of slant razors for my tree-trunk whiskers. The heads of these razors have a slight twist along the run, so the blade meets your skin at an angle, and helps to slice the hair a bit, rather than just chopping straight on. My slant razor actually feels quite a lot less aggressive than my old adjustable at max setting, but cuts closer.
Also, what brand blade are you using?
Gotcha. Yeah, Astra worked okay for me, but Feather is sharper by a mile. Might try that before getting a whole new razor.
