Do you ever stretch blade use beyond it's time even though you don't have to?

I never do this. Blades just don't cost enough to go through a bad shave.

Nope. I went through a lot of different blades to end up with ones I keep in rotation. I know how many excellent shaves I can get from one and stop there. It ranges from 4 to 30 shaves , the latter being with Personna 74's and "Light Brigades".

No. Never. There are certain areas of my face that contain very tough hair that goes in different directions. If the shave I get on other parts of my face is OK, but I can still feel the hairs on those areas even if I went over them 2-3 times, I change the blade the next day. The blade that has lasted me the longest with this method is the Gillette Nacett which was good for 7 days.
Haven't had a chance to try vintage blades as yet.

I'll do it occasionally, more often it seems if I'm using an "expensive" blade like a Kai. I usually go 6 shaves to a blade and don't wait until I see the blood or otherwise finding myself having to go over an area again when I normally don't with a sharp blade.

I think its human nature to try to stretch our resources. Its a result of our evolution, most of which humans spent in conditions of scarcity. We had to constantly make economic decisions that our survival and the survival of our group depended on. It was very bad to be wrong on major decisions. The fact that we are here today is evidence that our ancestors were right when it counted. I'm grateful for that. This trait is stronger in some people than others but our society still generally views wasteful or profligate behaviour as a character flaw. So now we might stretch that blade a few more shaves or eat that expired food because it really doesn't look spoiled. Personally, I love getting value - fixing things so that they can continue to be useful makes me smile. I have a 2002 Honda Odyssey that has 360,000 km on it (thats 223,693 miles) and I like that. I had originally thought that I could get 1M km but now that the vehicle is no longer the main vehicle it isn't accumulating the mileage like it used to so I'll be happy if I can get 500,000 km.

Having said that, my apparent fascination with shaving soap and related accessories is inexplicable.

Yeah we had a 2001 Honda Odyssey that went 160,000 miles. My kids grew up with that car and when we traded it in in 2014, it was like saying goodbye to a member of the family.

I usually get about 5 to 7 shaves out of a Feather when I have a beard, and 3 to 4 when I don't have a beard. I usually lose count of the shaves so I just go off of how it cuts. Blades are cheap enough that it's not worth stretching them imho.

Honda's run forever. Great car's.

I pitch the blade when the quality of the shave decreases. I find that by staying with it, a blade will often smooth out and become buttery smooth. A new blade feels very harsh in comparison.

Personnas in my Schicks are chugging along at nearly 30 uses on several and a Gillette 7 O'Clock SharpEdge is almost at 70 uses.

Not much anymore. Good points here. I feel fairly content using a blade until it's time to change, sometimes more..sometimes less depending on how it cuts, no stress. Enjoy your shaves.

Not to derail the thread but I know what you mean - that van took the kids to and from school from pre-school, it took us on summer holidays and it took my son and team mates to basketball tournaments all over and into the US. Both kids learned to drive in that van. My daughter is at university now and she had the van up at school for a few months. I asked her if she thought it was cool that the van that had taken her to her very first day of school, she was now driving to university. She didn't think so but thats fine because I did. When the time comes to retire that van I think I'll have a hard time with it.
