I would love to have that steel! Just can't justify spending the money, though. I do have two of the Bunker models. A 'steel that large wouldn't be very handy to tote around but it would last nearly forever!
One thing I like about the Bunker is that a large steel produces a huge amount of sparks with each strike. I can light a few stubborn tinders with my Bunker that won't light with lesser steels.
