. Watching that five minute video, you'll see that manufacturing disposable double edge razor blades is a fairly simple process completed by rather complex machinery.On Youtube, you can find short videos of disposable razor blade manufacturing like this one here
You need to hook up with an engineer who works in the R&D department of some razor blade manufacturer and develop a student/mentor relationship with him/her. Every manufacturer, no matter what the product, is always trying to increase their profits by lowering the cost of production or speeding up the production line without product quality suffering. That's a major goal of their R&D departments (among other things).
As a student, you will need to find out from your mentor what some of the problems are his department is working on to achieve the goal I mention in the above paragraph. Now, manufacturers of most products jealously guard proprietary information concerning manufacturing processes from each other, but you might be able to get your mentor to describe their problems in general terms. Coming up with real world solutions to those problems ought to be considered a successful completion of your class project. Discuss that with your professor.
So how do you actually hook up with this hypothetical engineer/mentor? You'll have to think outside of the box, but I'll give you a hint. Read What Color Is Your Parachute? 2012 by Richard N. Bolles. If the RIT bookstore doesn't carry it, you'll find it in your local Barnes & Noble.
And who knows? If the razor manufacturer likes the solutions you come up with for their problems, they might even offer you a job when you graduate.
Ggod luck with your project.
Namaste,
Morty -_-

Great video Morty, thanks for sharing! I'm curious, with regards to straight razors, do any companies forge them the way samurai swords were forged? Heating and folding and beating, repeat?

I would imagine you'll find the members who would have an answer for you on "The Forge" forum, under "Maintenance, Repair, and Restoration." Those are the fellows who use backyard forges to make razors from a hunk of steel.

Do a patent search to get a handle on the modern tricks of the trade.
Some razors on the market have patents on the box. Bring a magnification
glass to the store .... ;-)
The tricks they now use go on for pages and pages.
PTFE (teflon) is one critical coating. It has an interesting problem
well described in patents where the heat to fuse the PTFE on the surface
risks damage to the temper. Timing is critical or the batch stinks.
Other tricks are ultra thin layers of exotic metals (Pt and Cr) to help
control erosion and corrosion. Ceramic sputtering.. is yet another
trick.
Some blades are chemically etched to leave the thinnest polished edge.
Some blade steel is case hardened with heat and nitrogen rich
gas. There are some special edges that have vapor deposited diamond
coatings. Laser surface conditioning....?
There are other issues... speed, packaging, inspection, mounting,
guards, cleaners... and shave quality.
This is not a slam dunk freshman project... the art is fully developed
and rich in trade secrets and other intellectual property.
Heck look at "methods" to recover, reclassify and recycle diamond abrasives
in the razor grinding and honing lines with environmental improvements.
Or skip the sharp edge bit and focus on some other aspect of the product.
