I just watched this. It's great, thank you. The uploader wrote in teh comments
"After using my Gillette Fusion cartridge for 30 months now, I have found it necessary to use this arm rubbing technique almost with every use for the last few weeks. Today, I almost gave up on it, but I tried rubbing it on a pair of blue jeans as suggested by a different YouTube
video. Rubbed it backwards on the denim about ten inches about ten times, and the blade then worked just like new again. Now will I be able to my arm to recondition it again, time will tell."
COMMENTS ON ANOTHER VIDEO ON SHARPENING ON BLUE JEANS
"This totally works but I wondered why so I pulled out my 10x eye loop ( for examining gem stones) and examined 4 used blades over 1 year old before and after sharpening them. You can see that the leading edge of each blade is shinier after sharpening. The edge is maybe 1/128 of an inch but it is definitely sharper.
COMMENT
Informative video. Thanks? I did it on a smooth leather belt and got even better results.
Quite interesting! Will test that with "El Fidel" Model of Raz*War (razwar.com) and see it works too (5 blades model, high quality, now available in US too). Other good tip for avoiding blade becoming dull too fast: using SHAVING OIL. Really the best discovery ever made by me for my own shaving.
human hair is extremely strong, it wears down a 4 blades in about 30 uses, considering how tiny hair , if compared to the same size
wood human hair comes up to be thicker. I saw an example of this in How its made "blades".
go hardware store and buy honing compound or polishing compound with high grit. put on leather strop.
Safety razor handles and blades vary considerably in quality and "aggressiveness". An experienced wet-shaver with a fairly coarse, dense beard may demand a relatively aggressive blade and a comb-headed handle, whereas a beginner with a lighter beard may want to start fairly tame and work up to their comfort level if they feel they need a closer shave. The reviews on Badger & Blade
led me to get my first safety razor setup, and I couldn't be happier: no nicks, baby-butt-smooth shave.
To each his own. I learned to shave using cartridge razors like the Fusion, and have found that I get better and more comfortable shaves from an old-school safety razor. The next time a blade is starting to dull, I'll try your technique. It
should work as well with a safety razor blade. Cartridge blades are made as double edge blades that are then split lengthwise and fitted in the cartridge housing, so one type should recondition as well as the other.
