A Quality All-Purpose/Beginner's Razor
Size: 1 Count (Pack of 1), Color: Black Razor
These Zomchi razors tend to have pretty good ratings, but a lot of the reviews and interest in them is from women. As someone who has been shaving with a safety razor for many years now, it's awesome to see women getting into safety razors, but girls shave differently from us guys so I wanted to write a review as a guy.
*I will say it bluntly right here, if you are a guy or girl in the market for a safety razor, or are on the fence about trying one, buy this Zomchi razor right now. You won't regret it, and neither will your wallet.
This razor is great value for money. Beautiful design with nice machining. Construction is very sturdy and even the threads that screw into the head into are top quality. On top of that, the razor has a black coating that will prevent rust later down the road and protect the longevity of the razor.
Shaving my face, this razor gave me a really smooth, close, quick shave with a feather brand blade. I wasn't having to come back and make extra passes. It cut sideburns easily and got the difficult areas other razors tended to nick.
If you try the Zomchi blades it comes with and you don't like them, there are so many other brands available with different characteristics. With the right blade this razor will be amazing for everyone.
-Long story short, if you are looking for a quality razor at an affordable price that simply gets the job done, this is the razor for you.

Beautifully made.
Size: 1 Count (Pack of 1), Color: Fern Green Razor with Stand
If you’re trying to decide, just get this item. It’s sturdy, the color is gorgeous and it’s easy to load the blade. It does come with extras. You can also order large quantities from the company and they have a blade disposal can as well. Such a great design.

Quality, but OUCH!!!
Size: 1 Count (Pack of 1), Color: Rose Gold Razor with Stand
Major learning curve, cut the crap out of myself using it, but it seems like it’s made out of quality materials.

Perfect for Men and Women
Size: 1 Count (Pack of 1), Color: Rose Gold Razor with Stand
I have had this razor for about 5 years now. YES THE ORIGINAL RAZOR! The only thing I have to switch out is the blade. I bought a 100 pack razor blade and believe it or not but I haven't even gone through the whole thing. Of course after having it for so long there are a few things on it that have worn. Where you screw the head onto the handle gets stuck every so often due to the hard water. It has NOT rusted. If you are looking for something shard for that coarse hair this is it. Good for men and women!
