An OK blade but WHAT A SHOCK

RayClem

The Merkur blades are made by Feintechnik Eisfeld, which was acquired by the American company Harry's in 2014.

The Timor blades have the label "Solingen" which means they need to be manufactured in Solingen, which is in a different part of Germany.

Every now and then my wife will bring me home a shaving product she found while shopping.  Friday she handed me a package of blades (5 in the pack).  The brand was Van Der Hagen.  
[snip]So, about an hour later I went to their web site.  ...

Was that at www.vanderhagen.com?
You're relatively lucky.
Here's what I get:

Access Denied - GoDaddy Website Firewall
[blah-blah-blah]
Block reason: Access from your Country was disabled by the administrator.

Real professional. 
[edit...]
I had to start up Opera to see it, using the VPN feature.

No, I actually called the company and they were no helpful.

Do the Merkur blades still say "ice tempered"? 

It may well be that the production of Merkur blades has changed hands over the past few years. 
If so, I would consider that to be a very good thing.
