So far as I know, to date, you will not get the thickness you specify. It will be oversized. As an example, the 3/32nd I have been ordering is more like about 0.123 inch (about 1/8th). The S30V needs a few mill ground off anyhow and that may be a reason for the over thickness from the vendor. One foot??
I suppose you're asking if any of us have that on hand. I have 3/32nd (as described above). Pop's has some of the larger sizes and has more of my smaller sizes. Admiral is selling S30V now too at a lower cost.
Most vendors I have noticed sell minimum 18 inches, but I suppose one could specify any length at an optional cutting cost.
