This video shows a simple method of extending the life of an ordinary disposable razor blade for months and months and months. Razor blades are very expensive and most people use the blade for a week or more until it gets dull, then you change it to a new one. By using this simple 'Blue Jean Sharpening Method' it will extend your blade life and receive a sharp and smooth shave for months and months.. I don't know how long it will work as I am still using a blade that is at least 6 mos old now and I'm still using it...

When you finish shaving... walk to your closet... pull out one leg of a pair of blue jeans... hold the end with one hand and with the other simply stoke the razor along the entire length of the blue jean for 10 to 20 strokes... I like 20... then switch directions... the threads of the jeans run in a diagonal so switching directions allows for an balanced approach to fine tuning the blade's edge.

This is similar to using a straight blade on a leather strap... this is cheap or free considering you have a pair of jeans!

It will take the fine nicks out of the blade and allow for you to keep the blade very sharp.

I also sharpen the blade 20 strokes before and after each shave just for good measure.

I also blow on the blade to knock off any water droplets as oxidation/rust is the biggest enemy of a sharp razor blade.

If you want, you can drop your razor 'blade down' into a cup of rubbing alcohol to store it until next use to eliminate any traces of water.

This should save you tons of money... at the time of this video Gillete Fusion 4 blade pack sales for $13.99 + tax. if you generally get one week's worth of use per blade this will run you $167.88 per year + tax! If you get 6 mos per blade then you can extend your use for two years. The math works out to $7.50 per year + tax (two blades at $3.50 per ea)

Hope you get lots of shaves for free!

    Nice job on making it to the front page of reddit!

    thanks! this may be lame... but i had no idea what Reddit was!

    but it's really cool to see how many folks voted it up... cheers,


    Using jeans to sharpen the blades is simply not possible.To strop (maintain the edge of) a blade you need access to both sides of the blade(s) and that is not possible with a cartridge razor. Keeping the cartridge dry between uses will prolong the useful life of the cartridge.

    Dennis! Thanks for the proof - somewhere there is a thread on reddit where my video was up voted to the top but there were a few naysayers... Wish they could put this in their pipe to smoke. Cheers!

    Jake ty keep up the good work! these razor companies are a disgrace!

    you are so right! the jeans keep the blades so sharp it seems like forever, I have been shaving with a mach 3 same blade for 18 months, just try it! if you doubt it who cares keep spending money foolishly

    You could do all that that or you could just switch to a safety razor and get a ton load of razor blades for the same as Gillette cartridge blades cost. King Camp Gillette himself shaved with a safety razor made by his own company not a Mach 3 or even a Fusion Proglide Power.

    Sorry but you cannot remove a nick from a blade with a pair of jeans. What you end up doing is drying the blade to reduce the breakdown of the metal that results from being wet. mineral oil will do this as well. Leaving the blade soaking in alcohol is also effective.

    You might want to calculate how much it costs to run your hair dryer as it may not net any savings vs just buying new razor blades
