Parker’s Injector Razor Blades, 60 COUNT, Fits all Modern and Vintage Injector Razors - Made in the USA - Compatible with Injector Razors from Schick, Pal, Gem, Supply, Personna, Parker and More

Knowing how different brands of DE (Double Edged safety) blades can make a big difference in shaving, I order the only other two SE (Single Edge injector) brands I could find on Amazon, Parker and Schick. Parker is the least expensive (~$0.42 per blade) of the three brands and Supply (Black labels) is the most expensive (~$1 per blade). Schick is priced in-between them both at around ($0.72 per blade).I tested shaving with Supply, Parker and Schick, both new shaves (brand new blade) and longer-term (how many shaves per blade). Here's my personal experience and opinion. Schick is the sharpest, smoothest and therefore gentlest on my soft curvy skin. Schick also lasts the longest! Though I can get a full shower shave with the Supply Black label blade, I can't use it the next day to shave my face. Parker lasts longer than Supply, and seems to be about the same sharpness, as I couldn't tell a difference between the two with a new blade. Schick I can shave my face, do a full body and face shave the next day, shave my face again the next day and the day after. I'm not sure how far along I can shave my whole body again, but I will find out today, as I've already shaved my face, and plan on a full body shave later today.Schick hands down is my favorite blade, I also love that it is a full metal body for the injector, we need to be manufacturing less plastic, not more! Great job Schick, except for the plastic in the case (why even have it in a plastic case?) this would be a plastic free shaving experience.Photos are of the Supply Pro and SE, Supply black label injector, Parker injector and Schick injector. Happy shaving, thank you Schick, I'm one happy girl!If I take into account how long Schick lasts me, it's actually the most cost effective blade as well as the best shave (costing me an estimated $43.80 per year to have gentle soft skin that my girlfriend loves to pet and kiss and more ;).Background:Around a year ago I switched from cartridge razors (dollar shave club and Gillette fusion) to double edged (DE) safety razors. The result was much faster and easier shaving, less irritation, and much smoother skin. Then I purchased and tried different DE razors like the Rockwell 6c and the Merkur Mk34c. Also lots of brands of DE blades.However, as mush as DE shaving was a huge step up from cartridges, it wasn't without its problems, namely bleeders and the very thin DE blades couldn't last long enough to shave my whole body in the shower. I'm a transgender woman, and I have A LOT to shave! I shave my face once or twice a day and every three days I shave literally everything else (Full arms and legs, chest, and ahem many other areas). About half way through my shaving in the shower DE blades would start to get a little bit "pulling" instead of clean smooth shave.Then I discovered Supply Single Edge razors (the SE and the Pro, both Supply's 3rd generation razors). I promptly ordered both as well as Parker's new SE adjustable here on Amazon, Parker's turned out to be complete junk, terrible shave, really rough, lots of blade feel, skin irritated everywhere I shaved with it, it was horrible.When the Supply razors arrived, I was surprised and shocked at how amazing they shaved. I kept them both, and gifted one to my daughter (who loved it more than her DE as well). The quality of the razors themselves and the smooth and dare I say "safety" of them both were more than I had yet experienced.

For those that use a single edge injector razor, these are great!

So, these blades got a 4 rating, not bad. Right off the top, they are not as sharp as the Schick blades, and, the dispenser is a little stiff. But they are a very good blade that gets maybe a shave or two fewer. The real deal is the price, did I mention the price?

Excellent product at a great price.

Everything was right on

I'm so happy I went back to single-edge razors. No more knicks or cuts, and these last a month. The old multi-blade ones only lasted a week. (FYI: I have a thick beard and shave six days a week).

These don’t shave very close and leave nicks and cuts. I have used better blades purchased elsewhere. I won’t buy again.

On shave forums a lot of people recommend the Chinese Schick blades over these and I don't know why. I have used both in different Schick injectors and a pal adjustable razor and don't notice a difference in shave quality. Where I do notice a difference is price. These are way cheaper and you can buy more at a time. Plus they are USA made which is a bonus. The only thing about the Schick blades that would be better is the dispenser. It's all metal and a little more robust. However I don't find the parker dispenser to be as bad as some claim. I found it inserted with minimal force and no bending of the key.
