I know "when it gets dull" but how long does that normally take? I've used electric all my shaving career and only recently discovered the wonders of blade shaving. Started off using disposable razors only to realize, i don't know when to dispose of them! How long do you normally use a disposable or blade cartridge before replacing it?

When I shaved, a blade lasted me several weeks. When it started pulling, I put in a new one.

I wait till I get nicked, and then use a new blade.
..but I'm a cheap bastard..

I use a new blade each week (changing it on Monday morning usually, or Saturday night if going out). I shave 6 days a week. So my answer is after 5 or 6 uses. I use a Gilette Sensor Excel.

Well, I use a Mach 3 (Best Razor Ever) and I change the blade every 10 days or so - I shave everyday, and have thick facial hair.

I use whichever brand is cheapest when I go to buy them. Currently, that is Schick. (I've tried the Mach3 but noticed no difference, for me anyway). I must have tough skin or something, because I haven't gotten a nick in weeks or even months. So I just use them until they get so gunked up that it disgusts me; they're probably still sharp when I dispose of them after 8 uses or so.

I also use a Mach 3, but I change the blade every four to six months. I shave about six times a week, and I'm an average 42 year old man.

The difference? I shave in the shower.

Amy Dacyczyn in _The_Tightwad_Gazette_ recommends that you rinse and dry your blade after shaving. I've tried it, and it's made my blades last for weeks. I use cheap disposables.
Letters printed in the newsletter suggest sharpening the blade daily on the inside of a glass, or applying a thin coat of petroleum jelly to the blade after drying it. Or I suppose you could do both. You know, if you're really into that sort of thing.

From SDSTAFF Dex:Be sure the blade is sharp. You're not just cutting off hair, you're also scraping off a tiny layer of skin when you shave. A dull blade is more traumatic to the skin, making your face feel scratchy and look blotchy. Change the blade somewhere between every two and every seven shaves, depending on the toughness of your beard. Two weeks is too long to go without changing blades. Regardless of the number of shaves, if the blade is dulled, ditch it.Emphasis mine, of course.

I use disposables.

Every time I use a new blade I lose about a quart of blood on each of my first 4 or 5 shaves. So, no matter what anybody says, I ain't changing my blade after every 5 shaves!!!!! I'd be hospitalized within a month.

So, needless to say, I don't change my blade too often. Sometimes I'll even go a year before starting a new one. even after using the same blade for a year I still get a close shave and I never cut myself (until I start with a new blade).

You can cite dozens of studies if you like, you can tell me I'm wrong, but if I were to follow the expert advice on this one I'd begin each day standing in a pool of blood.

Well ditch the disposables and go for a multiblade swivel head razor you tightwad!

I have a light beard and even with a Mach 3 I think a week is the maximum. The longer you take getting the beard hydrated first the easier it is (no blood) and the longer the blade lasts. So, I can see shaving in the shower would make sense but I need a mirror so it's immediately post-shower.

Going weeks, months, years?!?!?! I have no idea how that works....

I remember once when I was a kid my Dad when asked what he wanted from my Ma for Xmas replied, "A years worth of razor blades so long as you nag me to change them every day." Back in the days when you could manually change them and swap sides to get two new edges per blade....

She got baby smooth cheeks to kiss for a year I guess.... :)

Mach 3 Turbo user here, with below-average beard thickness.

I use a blade cartridge until the lubriderm strip wears off, which happens after about five shaves.

In the novel Virtual Light, William Gibson has one character that keeps using the same disposable razor "because after a while they just don't get any more dull". Personally I change blades every week or so, but this Gibson line struck me because it's mentioned several times in the book, which I attribute either to really bad editing or a deeper truth. Since the character who keeps repeating this line is bivouaced on the collapsed Bay Bridge, I guess it's a statement about what's permanent and what's disposable.

Some disposable razors last a very long time. Which one are you using Max? wilkison lasts the longest I think according to some magazine article I read.

Your supposed to change the blades?

Maybe that explains some thing.

I'll be right back.

11-10-2003, 11:10 AM
You people are just plain freaky! The max for me is 5 days. Any more than that and I might as well just pluck the hairs out with tweezers because it would feel about the same. Dex and I are on the same page.

I use a Mach 3, shave 3-4 times a week, and change the blade at the beginning of each month. That's the only way I can remember when I changed it last.

11-10-2003, 05:12 PM
"Your supposed to change the blades?"

If they have new ones you can put in, yes.

My father used a double sided razor & I never could use it properly.

Once a week. I shave every day, even on the weekends, with rare exceptions. Usually I change the blade on Saturday, for some reason. If I've gone a day (or two!) without shaving, I'll only shave with a new blade. My beard is rather thick and tough.

Yup. I do that too. (When I'm not sporting the winter beard)Five days a week I use either the Mach 3 or the Sensor Excel, whichever blades were most easily accessible (I refuse to track down a store clerk to unlock a shoplifting proof case for some razor blades). I get about 20 shaves out of each blade. Only rarely does the blade get so dull as to be uncomfortable before that.

You gents who switch every week or less must own stock in Gillette!

Perhas this should be a new thread.
1 cutting edge disposables are intended for one time use. It maximizes the manufacturers profit.
2 cutting edges improve the shave.
3 cutting edges are just about the point of diminishing returns.
4 cutting edges overkill?

I use a body lotion or face lotiion instead of shaving cream, stay in the steam room at the health club for 10-15 minutes. Stretch the skin with one hand and press the razor head into the skin and move the razor along a path perpendicular to the cutting edge(s).
It is side slip or a slicing motion that draws blood.
