Just bought 2 packs of double bevel No Mercy heads and one of the packs had 1 Delta head.  This one probably missed the grind into a No Mercy. Anyone else run across this?

That's odd.  Never seen that, but I think you are right on how it happened.  I'm sure you could swap them out no problem, or maybe just keep them as a "one in a million" kind of oddity.

Or just use them all, Delta's are great heads.

I wonder if somewhere there is someone wondering why that single No Mercy is in with their pack of Deltas (after someone took one of each out to compare, and replaced them into the wrong packs) ?
