Keep them if the family member was close. They are of sentimental value & old heirlooms like that are always special. You might want to clean them up & also go to the library here & learn how to restore them. If you are interested in wet shaving, you will find that using a straight razor that has been honed & stropped properly will give you a much closer, smoother shave than the conventional 4-5 bladed cartridge type razors of today plus the cartridge refills are expensive!

These are some helpful links but you know what to do since you know how to use a computer, you can browse different ares in here & find all kinds of information. If you click on the large SRP logo at the top of the page, it will take you to the main page where you will find the straight razor database along with a lot of other things on the left side. The database might have some of the razors you have acquired & you can find out about them. If you are interested in this, it wouldn't be a bad idea to buy you a few books about straight razors as well which give history & dates of manufacture & so on. If you have any questions, please feel free to ask on the forum or you can even send me a message if you need to know something.
You will like it more than the conventional cartridge type razors plus they tend to burn & itch but a god straight razor or even a good old double edge razor with some good blades like Feather blades will give you a good shave. There are also more than just Feather blades that are of good quality & you can buy sample packs on Amazon & eBay to see which ones you like.
Good luck & I hope you decide to take up wet shaving.
