Long before Feather made their interchangeable blade, Weck made one. The blade look like a long and skinny Gem blade about 5 cm long. This was for their straight razor, but a Surgical Prep version made to look like a Feather safety razors of today. The purpose was to shave other parts of people, but many used them for face shaving. Two versions were made, one with a skinny rectangular handle, and one with a flat curved handle like a paddle. Both are very good and comfortable shaving razors.
