Learn all about double edge safety razor and razor blade: Double-edge (DE) safety razor remain a popular alternative to proprietary cartridge razors, and usually offer significantly lower total cost of ownership since they are not marketed under the "razor and blades business model". DE razors are still designed and produced in many countries. Better known manufacturers include Edwin Jagger, Feather, iKon, Lord, Mühle, Merkur..etc with several of them producing razors that are marketed under other brands. Often different models of razors within a brand share the same razor-head designs, differing primarily in the color, length, texture, material(s), and weight of the handles.Three-piece razors generally have interchangeable handles, and we Relax Technology Co., ltd specialized in manufacturing custom or high-end replacement handles.
The butterfly safety razor utilizes a twist-to-open mechanism head to make changing the blade easy and convenient. Variations in razor head designs include straight safety bar (SB), open comb (OC)(toothed) bar, adjustable razors, and slant bar razors. The slant bar was a common design in Germany in which the blade is slightly angled and curved along its length to make for a slicing action and a more rigid cutting edge.
A primary functional difference between double-edge razors and modern cartridge razors is that DE razor heads come in a wide array of aggression levels,where aggression is commonly defined as being less protection from the blade, which finally bring a more efficient shaving.
A three-piece British 'knockout' safety razor made from Bakelite and steel, probably from between 1930s–1950s
A safety razor blade, or just plain old, razor blade, was developped along with safety razor at the turn of the 20th century, and patented in year 1904. Safety razors gained popularity during the First World War when three and a half millions safety razors, along with 32 millions safety razor blades were issued to members of the US military in kits like below:
Upon returning home, the soldiers were allowed to keep their military shave kits. As a result, they easily retrained their new found shaving habit. This action turned the tide from the straight razor shaving, to shaving with a safety razors. Until nineteen sixties, safety razor blades are made from carbon steel. These blades had a tendency to rush quickly, unless they were dried carefully after each use. in 1965 a British company, called Wilkinson Sword began selling blades made of stainless steel which didn't rust easily. This enabled Ladies and Gents to shave with blades until they bacame dull. Now in the 21st century, many people are disgusted with the high cost of multi-blades cartridges. As a result, safety razors loaded with double edge blades are undergoing a huge resurgence in polularity.
Most D.E. blades are currently manufactured from stainless steel and have coatings such as platinum, teflon, and titanium, to make them smooth shaving or even more rust resistance. Certain double edge blades are even specified for using in hospitals for shaving patient before undergoing surgery. Blades are usally sold in packages of 5 or package of 10. Some companies offer special promotional packages with 1 or 2 blades included for free inside the package.Blades are also available in bulk 100 packs or sleeves as they are often called. Each sleeve contains one hundred blades.
Blades are often individually wrapped for safety, and to lockout moisture. Just remove the wrapper from the blade, insert into your razor and lock down by srewing back to razor handle or twist to close for butterfly safety razor, and you are ready rock and roll with your shave.
How long should my razor blades last: The rule of thumb is 3 to 6 shaves. So far people who shave everyday it usually adds up to a week's worth of shaving, from just one blade. With sharp blades option, you could even go beyond these numbers. Some factors that affect blade life would be: the brand of blade, how often you shave, how coarse your beard is, and your face prep prior to shaving.
What's the time to replace a blade: When you're shaving and your blade no longer glides along easily and you feel it grabbing and skipping instead of slicing cleanly through your beard. It is time to swap it out for a new one. DE blades are so reasonably priced that some people use a new one for every time they shave. Others feel that the second and third shave from the same blade provides the best shave for them.
Way to dispose used blades: Always keep your blades and other sharp items out of the reach of children. There are many ways of blade disposal. Don't just toss it in trash as is. Someone can push down on trash and injure themselves. When you open a new blade, use its wrapper to cover up the old blade. Wrap the paper around it and discard it. You can even take one step further, snap the blade in half, then throw in the trash. Many razor blade packages have a slot in the back designed for blade disposal. Just drop the blade into the slot.
Also, you can purchase a blade disposal case like this. Just drop it in. Easy and efficient.
