My son has a home work question, I would really appreciate it if anyone could help, I'll let him introduce himself and ask........

Hi my name is Rhian I am doing a topic about Victorians. my classmates and I have to provide a Victorian item I chose to do the straight razor as my dad enjoys straight razors so do you have any stories about them? Do straight razors have a Nickname? Why do we not use them commonly today? Why do they have a dangerous reputation? can you tell me about what they were made from and who made them? When and why did they change to modern day razors? If you can think of anything else to tell me about Victorian razors that I have not thought to ask please tell me.

Thanks for reading this
