The Fishbone 212 Double Edge Safety Razor is designed to provide a close, comfortable, satisfying shave at a fraction of the cost of razors manufactured by traditional technologies. The razor is light and compact, making it suitable for travelling as well as for your daily shave.
The Fishbone consists of two pieces produced by 3D printing technologies. In addition to these, you will need an imperial 10-32x3" flat-head machine screw and a matching nut to fasten the pieces together. The drive of the machine screw does not matter. Wingnuts are easily handled with wet, soapy hands, but you might also consider a knurled thumb nut with a flange for a classier look. If you wish to add weight or length to the razor, consider a coupling nut. If, for some reason, you cannot find these fasteners at your local hardware store, consider contacting your local research or industrial supply store. In addition to having a wider variety of fastener sizes, they will also have a wider selection of materials which might work better with the razor, such as brass or stainless steel. If you still have trouble finding a 10-32x3" machine screw, then you may substitute a 10-24x3" machine screw. Metric and imperial parts are not interchangeable; the angle of the head on the machine screw is different.
Unfortunately, Shapeways is a 3D printing service and cannot provide you with the hardware in the package.
As a gentle reminder, please keep wet shaving accessories out of the reach of children.
