Depending on your stubs you may need multiple passes. First with the grain and then across it. The last pass can me against the grain. Usually you’ll have enough foam/lathe for several passes anyway

That said, there is a huge variation og razors and blades. Some of them i almost can’t even look at without getting cut. Some razors have the option to adjust how aggressive they are. Shaving foams also change the experience basically and even you method of whipping up a foam/lathe can make a difference.

Its not as straight forward as it seems but once you find your way it is pretty easy. Take your time with it though. Shaving slowly is still pretty fast often even compared to electric shavers when they dont really take all the stubs
