Marketing fact check
I am the sort of person that disassembles tools upon purchase to make sure all the claims on the packaging are legitimate. I recently purchased these
and want to test the claims. My initial thought was to disolve them in acid and send them for commercial analysis, which I will do unless anyone has a
more home lab option. As there are no claims on composition it is just a presence absence test. The platinum claim is my biggest interest. Does anyone
have a good presence absence test for platinum? Thanks in advance for any assistance.

As an aside, here's another vaguely labeled product. Like some products that say made with canola oil, sunflower oil, and/or cottonseed oil.
Printed near the bottom of this half gallon carton ...
"Blended with Valencia orange juice, from concentrate and not from concentrate."

p-nitrosodiphenylamine can be used as an indicator for platinum, palladium, and rhodium.

I noticed the Derby blades use a polymer and these Treet blades use specifically Teflon as well as platinum and chromium like the Derby blades.
"A high quality double edge razor blade, this super stainless blade has a special edge treatment of platinum chromium and PTFE that enhances the
durability, smoothness and sharpness of the blade, providing optimum shaving comfort and satisfaction."
https://www.amazon.com/Treet-Platinum-Stainless-Double-Blade...
At any rate there's a lot going on with the Derby blades - chromium, ceramic, platinum, tungsten, and polymer coated edges. It will be interesting to
see if you can detect some scant amount of Pt in the edges.

This afternoon I broke the cutting edge off one of the razors and performed the test as described in the paper provided by josh1037. I did not get any
hint of purple or red on the paper. I am currently in a covid19 office ban, but when I am next in I will submit a sample for laboratory analysis and
see what comes back.

glad some one is out there holding them to account of their claims! we need more like that, so much bs marketing, there needs to be a wave of people
suing them over it befor it gets back to honest again.
Next we need to demand actual info on damned boxes! I don't give a crap about marketing give me info on the Fing product! Volts, Amps or Watts, some
thing useful.

What's vague or confusing about that?
It's blended with Valencia orange juice from concentrate, and with Valencia orange juice not from concentrate.
Sure, it should say blended with Valencia orange juices from concentrate and not from concentrate, but copywriters aren't the sharpest tools in the
drawer and seldom up to understanding the fine points of the use of countable and non-countable nouns in English.
Various monies have been allocated to the educational system to solve this problem, but educators aren't always the sharpest tools in the drawer
either and they keep returning the monies because they think somebody is making fun of them by calling them, 'monies'.
As for the platinum, how sensitive is that test?
If I were going to put platinum on blades just for the bragging rights I'd sure use as little as I possibly could.
I might even go homeopathic: "treated with 60X homeopathic dilution of platinum."
