They use something similar to that for surgery prep.
Don't know about that particular one, but I use a Laser Click. Pretty much identical to several other "Click" razors on the market. Similar to the one in the picture, they are one piece injection molded razors, with a molded hinge on one end of the head and a clasp on the other, which allows the top to flip up for blade replacement. More like a semi disposable, IMO. The one I have is translucent blue, not institutional looking like the one pictured. It also has a safety bar design more like a Tech (for lack of better example) than the one pictured, which reminds me of a Merkur adjustable. It's also an ultralight, weighing at .23 oz with blade. Compare with a Merkur 45 bakelite, at .53 ounce with a blade, known as a very light razor, the Click is about half that weight! A Bic disposable, OTOH, is lighter, at .17 ounce.
I find it's a perfectly decent shaver, the results similar to what I'd get from my Merkur 45 or Feather portable. Despite the softish thermoplastic construction, it's very well designed to hold the blade securely and centered, with the edges perfectly parallel to their safety bars as long as the latch is completely closed. One interesting characteristic I've noticed about the Click: it "sings" similar to the way a Gem 1912 does. I'm guessing the lightweight and mostly hollow head acts like a little resonating chamber, making audible the vibrations of the blade.
I've seen nearly identical razors currently sold with the Lord and Gillette name, sometimes even called "Click" razors. If you could find one for cheap, and these do seem to sell extremely inexpensively in or near their countries of manufacture (the Laser is made in India), they are worthwhile users and curiosities for the shaving enthusiast.
