Real men shave with a razor holder they print themselves. Sorry Gillette.
It works - the picture is of me having just shaved half my face with it.

To print: top, bottom and handle prints
m3 nut and screw.
- Print the 3 STL files on your favorite open-source 3-D printer.
- Place an m3 nut in the nut trap in the handle.
- Place a double edge blade on the top piece as shown in the picture in red.
- Then place the bottom on it and squeeze - the metal blade will bend slightly. This needs to happen to angle the blade so it is good for shaving.
- Push the m3 screw through the sandwich of the top, blade, and bottom - and then screw it on to the handle.
You have now just made yourself a safety razor that retails between $20-80 online.
If you never shaved with a safety razor before - ask your grandpa how to do it or read the Art of Manliness http://artofmanliness.com/2008/01/04/how-to-shave-like-your-grandpa/
or Life Hacker http://lifehacker.com/5313711/learn-the-economical-art-of-wet-shaving http://lifehacker.com/197065/introduction-to-traditional-wetshaving
or watch a demo on Youtube
<h1> Economics: </h1>
A 10 pack of Merkur Double Edge Platinum Blades cost about $5 - or 28 cents per blade on Amazon. The plastic for the print and the left over m3s you have from building your RepRap are basically free. A normal guy might go through one double blade every two weeks if you switch the side you are using. So blade costs for safety razor shaving is about $7/year.
Gillette cartridges are around $10 per cartridge. The website http://www.realmenrealstyle.com/learn-to-shave-like-man/ puts the cost of shaving using drugstore blades at $300/year. In fairness, Fortune reports that Gillette says they last 5 weeks, which only puts costs of just the cartridges at about $104/year instead of $300. You can judge for yourself based on your own blade life.
So if we use Real Men's numbers and assume men start shaving at 10-15 years of age and live to about 75-80 - you can estimate about 65 years of shaving - which would save you about $19,000. Not bad.
I noticed that cut hair tends to get trapped in the ridges in between layers Ã¢â¬â so this is yet another reason to improve open-source 3-D printer resolution.
I just made this so I don't know how often you need to print new components.
The printed razor holder is obviously much lighter than the traditional steel variety- I actually like this, but you might want to mess around with fill settings or design to get something you like. The OpenSCAD files are included. They are a bit crude and not quite parametric - apologies. This is a start at what could be a really good replacement product.
Next version - put the tabs on the bottom, then can thin the top and make it curved for a closer shave. You can get the same effect with the curved top but this is hard to print.
I would love if someone hacked this and made a women's razor.
