THE SHAVE FACTORY 50 Feather Double Edge Razor Blades, Yellow

Very sharp, even for a razor blade. Fits any safety razor and works exactly as you'd expect. Skin irritation is minimal and safety is as you'd expect, but these do widely vary by the handle. Easy to use but because they're so sharp they're unforgiving of mistakes, so it's easy to cut yourself. These are around 4 times the price of a budget razor blade, but they're worth every penny. Glides through my thick and rough facial hair with no issue, generally good for at least 4-5 shaves but you could get more if your hair is thinner.

First time using a double sided blade and these were the razors I picked - so glad I did. Amazing sharpness - I easily get two weeks out of one blade (and I shave every day with strong stubble) - very impressed. SOOOO much better than cartridge razors! Never going back.

These came fast delivery and they are exceptionally sharp , and a great quality

The best blades on the market in my opinion. They last for 8-10 shaves with me, and have an outstanding rigidity to them, staying perfectly straight in the razor, without even small up and down bending, allowing for a great close shave. Only gave it four stars as I think it could be more competitively priced, with less long lasting blades still coming out to better bang for buck being much better priced

Reliable, cost effective

Decent quality, good price

for my money, these are right up there. nice and sharp and do a nice shave. certainly better than gillette or wilkinsons. They are my go to every time. been using them for quite a few years now. I shave 4 times a week and get roughly 2 weeks out of a blade. it will be dragging at that point but that’s just me getting a bit more out of it. (i have a 60 year old face, so it’s used to a bit of torture)

Best blades, I've tried them all. These are the best. Make sure to dry off by loosening your razor after use, extends life of blade.
