If so, you realise that a warped razor with a flat spine is still a warped razor ?

Not sure if you were referring to my posts. If yes, I have to say sorry that I confused you. As I mentioned earlier, all 3 Dovo came with geometry issues in different magnitude, spine issues were the least of the concern.

I guess both of mine were Sheffield's, and exact same behavior.

No worries. I guess I misunderstood what you meant by " spines in different magnitude"
Dovo released warped razors in the past so I assumed

For me 90 years is certainly vintage but they are pretty consistant from the age bracket I stated.
I have always advocated the same for learning - start with tape and learn, then remove.
I believe its the best advice one can give to someone new, assuming goemetry is good of course.

We all know the adage about dog years. In the same line of thinking but with the opposite direction we can consider tree years. I have often pondered the exact meaning of "lifetime warranty." Are we talking about a bristlecone pine's lifetime or a fruit fly's? Perhaps when it breaks, that was the end of it's lifetime?

Straight razors should last for centuries. That being the case I wouldn't consider a 90 year old razor as old but more post adolescent. Straights in the form that we know them have existed since at least the 16th century although not many that old are still around or at least not still in use.

I don't really consider any of mine as "old" unless they are pre 1870s. You are right though that ones made from the early mid 1900s on are more consistent. I think manufacturing was more controlled/controllable once that century mark passed. It seems especially so after WWI; funny how wars seem to move us forward. It's a sad thing that we seem to be at our zenith while seeking to destroy each other.

I once received a flashlight for a Christmas gift that said "Lifetime Warranty" on the box. Reading the fine print it said that the product was warrantied for, and I kid you not, "the life of the flashlight" I've laughed about that memory ever since.

I meant "spine issues in different magnitude". Missed "issues" somehow. I never imaged I could see so many different issues on a single razor. Spine issues are relatively easy to fix but a warp edge is beyond redemption. I eventually got it shave ready, but there was way too much trouble. So Dovo really deserves the reputation here. And I wish I had seen those sooner and would have walked away from it.

Lol, if I remembered correctly, PNY did the same with their thumb drive warranty...
