We have discussed this at length before.

My take has always been, it's because everything about the razor is absolute perfection. The ingot it came from was perfect, the tempering, forging, the guy doing the grinding and everything else in the fabrication is all perfection. Razors like that are rare, very rare. Many think they have one like that but they don't. if you do you will know it.

It has nothing to do with the brand or where it came from. I had two TI's from the SRP LE edition sequentially numbered. One was one of those razors and then other was far from it.
