Photos Some tiny knives I've picked up recently

Here are a few interesting tiny patterns I've picked up recently.

Sorry for the camo. It was the closest thing near me when I took the pictures

J.A. Henckels: measuring about 2.5 in. MOP covers, but cracked on one side.
It may be made by Boker since it is missing the "made in solingen" mark and I'm unsure about the vintage.
Half stops on both blades and coined on the spine.
The grinds and details are amazing for a knife this size.

Whale: Was sold as having genuine tortoise shell, although I haven't done the hot pin test.
Half stops on the secondary but not on the primary blade.
Has some gold leaf(I think?) behind the tortoise shell.
Main blade has a picture of a Whale and "Whale" stamped on it. Below has something else, but its too small of font and partially obscured by the scale to see.
Backside has "Magnetic forged steel made in Germany"
No Idea of its age.

DeLarue&Co: Absolute mistery to me. Couldn't find any info on this one.

Very nice collection of executive/gentleman's/business knives from the days folks still had to trim the quill of their ink pen a time or three a day.
Nice score.

I think a German cutlery maker, Richartz, used a whale tang stamp. Here's an example that I have:

Never seen a knife with the multiplication table on it before.
Appreciate the info. Any idea how to figure out how old it is? I'm used to dealing with Imperial/Schrade and Camillus and they're well documented, but I can't find info other than the trademark for the whale that was filed in the US in 1954 and expired in 1996. Link

Yeah, this was the first knife like that I've ever seen. (Since I taught math my entire career, I was thrilled to get the knife! )
I don't know anything about dating Richartz products; I've never seen a Richartz "tang stamp chart" like you sometimes see for other knife makers, showing what tang stamps were used in what years.
But Richartz is still making knives https://richartz.com/en/ and still use a version of the whale, kind of abstract or stylized. Maybe you can use the email address listed there, info@richartz.com, to see if they can give you more info on your knife.
