I am guessing their is a reason. Some have offered the conjecture that the leather is not flat, and the x-pattern mitigates it. That could be. But a side effect is the edge closest to the the monkey tail spends less time getting stropped than the edge further down.

I've been thinking that maybe there is more to the x-pattern than simply covering the entire blade on narrow strops. I reason that if the stropping can push the micro serrations together front to back to get a sharper edge, it can also curl the micro serrations away from the monkey tail if you do an x-pattern. I've made a gif to illustrate what I mean.

Does this make sense?

Apologies for the two images. I am not sure why the blue background attachment is displayed. Is there a way to delete attachments?

I have absolutely no idea.

I tried to think through this one in my head, and it started to hurt.

Technically then, wouldn't these micro teeth also move forward and backward from the friction and contact with facial hair. This is much too scientific for me.

The only argument that I could come up with is that the teeth might be weaker "left to right", as it were, than "up and down". But that is just a flat ot guess

I have never seen teeth in a magnified image of a razor. I have seen striations along the bevel, but I have never seen an edge that looked jagged unless it was damaged - am I missing something?

Yeah, post 5.

Or you can look at the pictures from the popular mechanics article in early 1930s and the write up by verhoeven in I think the 1990s. They should both be in the document section of the wiki, or at least there should be links.

How about using the X pattern, so the whole edge is touched evenly, or the Race track pattern, or why not just try and go straight back and forth.. Honest yer not that good to do is perfectly that an uneven strop is going to matter much :) unless it is really uneven then that needs fixing...
The X pattern was developed because strops were thinner and still can be so if you get in the habit early then you never have to worry...Just make sure the entire edge is touched by the leather and your fine ...

By the way if yer edge really looked like that at anything under very very high magnification the strop ain't gonna help much :rofl2:

I looked and couldn't find what you were referring to. Any more details I can use to search, or do you already have a link? Thanks!
