I recently found this 7 days set made by a Belgian maker
Guess the owner never shaved on a friday...
Saturday blade is stuck however
Used WD40 to soak but still too tight to remove, even with some gentle tapping and the use of a viseAttachment 312098Attachment 312099Attachment 312100Attachment 312101Attachment 312102
Will soak a bit longer, there ought to be a way to have the blade released
