Thread: Ok now Im just confused

Possibly your pastes are creating or sustaining a slight wire or burr which quickly fails, unless the steel itself is not capable of holding the edge for some reason.

Excluding the factors that onimaru55 listed, which are valid points, ineffective stropping is likely the cause. What you are experiencing isn't uncommon for new folks, most will restrop mid-shave to fix this issue. As you practice and gain experience you'll find the need to restrop will become less until you'll eventually be able to finish a shave without the added stropping.
