“Ridiculously sharp is an understatement. I’ve been straight razor shaving for around eight years but I’m having to learn a kamisori from day one. The first blade hasn’t lost any sharpness yet after four shaves.
Be very light on pressure when you start to use these as they will cut quite easily. Have faith though they will give a close comfortable smooth shave with much less effort than a straight razor. Definitely worth the money before you decide to buy the more expensive ones. The only downside is these come in just a small cardboard packet so there’s nowhere to store these for safe disposal.”
“Purchased the Barbarosa Bros. Cut throat disposable blades with my non folding kamisori razor.
The blades are extremely sharp & give a very close shave.
The price is a bonus as they are cheaper than other compatible makes.”
