I keep seeing discussions of "rotations" of everyone's shavers... so I guess my question is, how often should I switch razors? I'm especially keen on extending edge life of each razor yet setting up a pattern such that when one needs to hit the hones (which for now, at least, means I'll have to ship it out) and still have one that shaves smoothly.

I have two razors, a duck Satinedge and an Ern no.126. Currently I favor the Ern as its light weight seems more manageable especially when I attempt to scrape the dome (I have yet to have a nick-free head shave off the duck). But should I really be leaving the duck in the drawer with a coat of oil (its current state)?

My current plan is to wait until its time to ship out the Ern for honing and then break out the duck and then be using that; I figure that by the time the Ern is returned I will be used to the duck's heft and it'll be my "favorite"...until it needs to get honed and and the Ern takes its place, becomes a "favorite" and the cycle begins anew. Ad infinitum.

But in the shave o' the day threads, it seems the same guys have a different razor every day...should I be doing that instead?

Thanks!
