Well, I used one razor daily for several months when I first started and there was no problem at all with that.

I dont think the razors need to rest at all. Just make sure you totally dry the blade and keep it in a dry place when you store it.

I also strop after my shave as well. Now that I have two strops, I'm midway through converting the old one into a pasted one. Just waiting on my CrOx for the leather side..!

I do 25 webbed fabric and 50 - 60 leather before each shave, then 25 linen with chalk paste (on the old strop), 10 webbed fabric and 15 - 20 leather afterwards (back on the new one).

My theory is that the linen and chalk will help polish out any damage that has occured to the edge during the shave. When I used this material daily it really helped to keep my edges sharp and I dont want to stop using it now I have a new strop. Nor did I want to paste my new strop, hence the odd stropping routine!

I experimented with doing the canvas before the shave as well as after, and found it made no difference. So I just stuck it at the end to spread the stropping out into before and after...!

Anyway, after that little novel, I dont think its resting that keeps the blade, its maintenance. Use a good strop, dry the blade and store it correctly and you should have no problems!
