I've been a Mach3 user for the past few years, so am not entirely convinced by these blades. However, they ARE incredibly sharp as you can see in my photo (Ouch).

I'm new to cut-throat razors so my technique will need several weeks of honing to give an honest opinion.

Derby blades are easy to fit, lightweight, cheap and I'll say it again - they're very sharp.

Arrived sooner than expected, and that with free delivery.I’ve used this brand before and the shave from them are brilliant, extremely sharp so be very careful, but these blades always fit perfectly in my cutlass razor and leave me with a nice clean and sharpe finish to the shaping up of my beard, moustache etc.. would recommend and will us seller again tho that won’t be for sometime as I’ve got 100 blades to keep me going for ages!

For the price I could use more often but I use each blacde once then change for new one so always get sharpest they can be and they are Sharpe you can cut yourself by accident before you even feel it. And I get less razor burn as they only need 1 pass and not much pressure so as long as you have prepared for right they wil leave you smooth and also no red and sore. Which is always a bonus unless you like that sort of thing.

Overall I haven't had any problems, the razors have fit both of my straight razors and I haven't had any of them chipped or snapped when I'm packaging them would recommend and great value for money

Cheap blades. Do cut okay but they are not as sharp as Gillette blades. These blades didn't give me a real straight line on my beard. I'd pay a little more and get some better blades

i was using different blades before.they were smooth and sharp didn't feel anything on my skin.but these blades are not so sharp .you have go twice to get all the hair.which is not very practical and good for the face.

Very good sharp blades at a great price. If like me you are using for tge first time for straight raser shaving. Do yourself a favour and watch a YouTube video on it and you will find it easy not to nick yourself I made the mistake of watching a video after my first shave :-(

These are excellent. I bought several packs. Fit easily into shaver and can use multiple times especially as double sided. Haven't bought razors for ages (at £18 per pack) and won't need to. Really good close shave (and a decent one if in a rush).

Also due to the type of shaver I have which is similar to a standard type razor (not the barbershop type) it means you use the same grip / technique as a standard razor and so don't really risk cutting yourself. Yes a couple of nicks when not fully concentrating.

When I (eventually) run out in a year or so I will definitely be back for more.

Great value for money, Not the sharpest blades but well worth the money

I needed some blades for a new cut throat razor so I found these and they were exactly what I needed! I comes with loads which means they will last ages so I won’t have to go out and buy loads! They come in a handy little box and already snapped so no need to snap into size and very easy to fit
