I have my grandfathers Swede, so it is maybe closest to priceless, but after all it is just an excellent shaver and that's all about it.
Most items have their prices. I think there is no single thing i own i wouldn't sell if things went that way and if the price was right.
And what it comes to fire they are just items after all. Of course i would be dissapointed but sooner or later i would pick myself (at least ) 2 or 3 razors and kept on going.
