could this be????????

Twist to Open Handle for Single Ring Brass Gillette Double Edge Safety Razor | eBay

Isnt this a key for the saught after gilette psycho razor used in prisons and psycho wards????? its deff not a single ring tto :thinking:

Actually it was available to incarceration facilities to assure that the inmate did not make a weapon of the blade.
Saw this on a thread long ago.

yea, isnt that the key to one? those keys are highley sought after for every dozen razors only came with one key, and the razors are hard to find and people do make their own key for them but an original must be hard to come by

Looks like part of a 1908 single ring.

The middle is the psycho key that I have seen.

So, this was a security measure that allowed Institutions to provide razors and blades to their guests without allowing them to remove the blade? Key needed to open the cap?

Cool
