How short is too short?

I have a few badly chipped blades that I was going to toss, but after a few trips to the butchered blade thread I got a little more inspired. So they may become shortys. The questions I have are

How short would you say is too short? IE no longer comfortable/practical/balanced, etc.

What is the shortest blade you own? How does it perform?

To be clear, I'm talking about blade length (usually about 3") not width. Thanks in advance!

When I sit at the plastic booths in McDonald's , my feet don't touch the floor. :(

I'm not sure there can be a blade too short, as they can be used for trimming around beards. A shorter blade just means more strokes.

I have a Max Sprecher shortie, it's an 1-1/2" blade length, it's a blade I have done full shaves and trimming, I don't know if it makes a difference, most guys don't se the whole blade anyway, but I find it comfortable to use. Most Kamisori are only 2". Tc

theres your answer right there
a lot of Japanese Str8s are only 2.5" about,
also a Shavette (DE) blade is only about 1.5" so anything from there up is still good for daily shavers,

I have a shavette with a DE blade as well and it's great. However the overall is similar to a straight. I worry that if I trim back a straight razor below say 1.5" the balance will be all out of whack. Of course... they would have been trash anyways...

Good ? For Your Wife,,,,Ty

I've made a few shorties.
My smallest is just slightly longer than a single edge razor blade, and quite comfortable to shave with. (Top right) And two straights that are shorties, but were made that way.
The first being the one Joseph Rogers & Sons (bottom left)

I thought something looked different about this razor when I bought it, but didn't find out till I set it next to some other's on the work bench.

But I don't think I'd go any shorter than my shortest one. JMO

If you think about it, you really only shave with about 1 inch of blade, at a time…

I think some of those shorties in the past found use in the Project Coochie Razor thread, perhaps the greatest thread in SRP history.;)
