Don,
Yes, one of the ones shown there.
I already have the Klean Kanteen 12 ounce bottle and 27 ounce bottle (excellent water bottles, by the way) shown on that page, but I am thinking of the Guyot Designs 38 ounce stainless steel bottle.
I'm considering moving my PSK into one of those because I think it would be truly watertight, would be better for use as a water carrier, and would be better for use to boil water or cook, in comparison to the aluminum Sigg box I'm currently using. Additionally, it is longer, thereby perhaps allowing for putting a 5 inch fixed blade in the kit, instead of a 3 inch fixed blade. I'd choose it over my Klean Kanteens because it has a broader base (useful for stable cooking) and thicker walls (more durable, and holds up better to cooking) than my Klean Kanteen, and also has a wider mouth than the Klean Kanteens, making for easier packing and unpacking of the kit. I'd choose the 38 ounce because it has the greatest volume for storing my gear (still pocketable, for me, and actually almost the same volume as the box I'm now using).
I'd been considering moving my kit to one of the Guyot Designs 38 ounce steel bottles ever since my brother showed me his Guyot Designs steel bottle. After reading this review...

...and getting confirmation that it can stand up to some cookfire use, and learning that it has a rim for modifying it (i.e., so I can drill a couple holes, for hanging it from some wire), I think it sounds like it should fit my use well.
