How are safety razor blades best?
Double-edge razor blades all look really similar, but they’re not homogeneous commodities like sugar or corn. In other words, they are doing have some distinguishable features that make each brand different.
They do however all share an equivalent basic, fundamental design. Which is quite important because if they didn’t all have an equivalent basic size, shape, and dimensions, you’d be limited on which blades would actually fit and add which razors.
And because all of them have an equivalent universal shape, design and fundamental features, there’s not tons of room for creativity within the manufacturing process.
There definitely are some manufacturing differences from brand to brand like composition quality of the metal they use or how the blade is sharpened and polished or what chemical coatings are applied. But the particular process of how DE blades are manufactured is pretty consistent.
The Manufacturing Process
The double-edge razor blade manufacturing process starts off with a strip of chrome steel that’s many feet long. This strip of fabric may be a metal composite, thin, extremely light and has dull edges.
The composite starts off very soft and versatile, therefore the initiative is to harden it. the fabric is hardened through a process of progressively heating it up then cooling it backtrack.
It depends on the manufacturer but it commonly takes around 4 rounds of heating and cooling to urge the merchandise to the optimal hardness. the top product blade must be nice and stiff, not flexible, so this is often a very easy but important step within the process.
Once the merchandise has reached the optimal hardness, it’s then sent through a series of grinding and polishing machines. the aim of the grinding machine is to sharpen the sides while the polishing machine cleans up the sides by removing any imperfections.
Both the grinding and polishing procedures are incredibly important. Grinding the sides is what makes the sides sharp so it’ll cut the hairs right off. The polishing step smooths out the sides by removing any burrs or stray fragments from the cutting edges. DE blades got to have sharp but smooth edges to make sure they will cut the hairs without cutting the skin. One feature without the opposite renders a blade unusable and possibly dangerous and safety razor blades best.
At now within the manufacturing process, the merchandise that started as an extended, dull strip of sentimental metal is now thousands of sharp individual DE razor blades. they’re not done yet though! Now they have to be coated and treated with a spread of lubricants and finishes.
The first coating applied is usually a chromium-based coating. it’s applied to the whole blade but is meant to make sure that the cutting edges stay hard resistant and safety razor blades best.
Next, a non-stick coating is sprayed on. The last item you would like is for the blade to cause tons of friction, you would like the blade to only glide across your face. The non-stick coating helps reduce the quantity of friction between your face and therefore the blade which helps prevent skin irritation and razor burn.
Lastly, the blades are submerged into an oil-based solution that helps provides it some added protection from corrosion. Corrosion is the primary contributor to blade deterioration. Blades typically only last 4 or 5 shaves, but any added protection from blade corrosion is usually helpful.
We overlooked tons of little steps within the manufacturing process like when the chrome steel gets dig individual blades, when the brand logo gets applied, how they’re packaged, etc. But we expect this could find safety razor blades best offer you an honest overview of how the manufacturing process is straightforward and easy.
Key Takeaway: Not All DE Blades Are Created Equally
So what’s the key takeaway from all this? There’s not tons of flexibility with regard to different features, but that certainly doesn’t suggest all DE blades are an equivalent.
Think back, what was a number of the manufacturing steps which will affect the standard, sharpness, and performance of the ultimate product?
How sharp of a grinder was used?
What is the composition of the metal?
What lubricants and protective coatings were applied?
How fine was the polishing?
No, you are not going need to research answers to those questions just to seek out the proper blade. But it should cause you to think. What should I try to find during a DE razor?
