I must say that it's a time consuming and labor intensive process , since Mastro Livi virtually makes everything by hand , and if he does not , he still needs to adjust practically everything to the razor being made . After finishing it , Mastro Livi and I decided to proceed with a shave ... well , what can I say , this scary looking razor delivered a silky smooth shave , exactly what I wanted and nothing less . I wish to thank Mastro Livi for the wonderful experience he gave me this past saturday and I look forward to watching the edited video .
