OneBlade HiCarbon SE Safety Razor Blades - Replacement Blades for OneBlade Element, Genesis, Dawn, Core and Hybrid Razor - Single Edge Blade for ShavingCompact by Design (Amazon-developed Certification)

Short Version: This is the blade that should have launched with OneBlade 10 years ago. If you are a OneBlade user and have only used the Feather FHS-10 then you need to buy this blade, it is superior in every single way and you will never want to use the Feather blade again after using this one.Long Version: I will be making many comparisons to the Feather FHS-10 blade in my review as it is "officially" the only other blade that works with the OneBlade and think its a perfectly fair comparison due to only 2 blades existing in the system, I am aware of people who use modified GEM blades in the razors but since this is not an official blade it will be outside the scope of this review, a simple search will tell you all you need to know if interested.When I heard several months ago that there was a new blade for the OneBlade system that was made/commissioned by OneBlade itself it had me finally interested in purchasing one, I finally pulled the trigger when I was able to acquire the razor with a decent discount, it came with a 10 pack of OneBlade and FHS-10 blades.Being an experienced DE (Dual Edge) shaver I am familiar with a wide variety of blades and know what is sharp and what is not, ironically, it is Feather that makes the sharpest DE blade in existence but their are many others which are close such as Personna CC (Accutec), Wilkinson Sword DE (Germany), and King C Gillette, these are not as sharp as a Feather DE initially but last far longer.I decided I would use the FHS-10 first when receiving the razor, despite knowing its reputation outside of the OneBlade propaganda on its website which has since been nearly erased at this point, I knew it was going to be rough. Bottom line, if you are used to performing an 3 pass shave with a top quality DE blade, the FHS-10 will barely make it thru one shave, and the final AG pass will be rough, even trying a second 3 pass shave which I did with multiple blades in the 10 pack was consistently dreadful and almost dangerous, the blade was so dull that it nearly locked up twice on me going AG despite being well lathered up. I truly don't understand how or why a company like Feather makes such a ridiculously dull blade unless it was intentional when they made the sharpest DE blade on the market.Now for the good, the OneBlade blade was IMO designed to be "the" blade to use for those with a OneBlade handle, they clearly realized the FHS-10 was a liability to their system and to be perfectly honest I think only their aggressive marketing along with recently switched over ignorant cartridge users was the only reason they stayed afloat prior to its release, those users don't know what actual sharp is even if the marketing told them so.While the OneBlade isn't as sharp as a Feather DE it does rival those next best DE blades, when I retired my first OneBlade blade after six 3 pass shaves it was still sharper than a brand new FHS-10, I suspect I could have taken it beyond 10 shaves and it still would have been better...So if you have a OneBlade razor and have only used FHS-10, get these blades now, you will not be disappointed and will know true sharpness finally in the system, they are cheaper too!

It's not only about cost-effectiveness, but the quality has also improved. Edge sharpness retention improved significantly - I used to consume one FHS-10 blade per week, but now this one lasts longer, I'd say like by 50% at least. Very satisfied.

Sensational blades. smooth, comfortable no pulling. Great price.
