I know that Admiral steel carries sheets of 440, but not sure if the sizes match what you're seeking. Most of the stock they sell is sheared from sheet or rolls.
If you've not purchased it before, be ready for severe sticker shock.
Here's a link to their page on 440C:

Ed,
First let me say thanks for your response. I'll check them out. Although I already looked at their website I didn't call them because I didn't find that they offered it in sheets. As far as sticker shock, I'm not sure how, but I did manage to get past it.

Second, let me say ... Wow! I have been admiring your knifemaking expertise for many years and am thrilled to be "rubbin' elbows" with you through the forum. I love the internet!

Third, I'd like to say "Thank You" for all the enjoyment your work has given me over the years.
TRUE Craftsmanship, Sir. :thumbup::thumbup::thumbup::thumbup::thumbup: There have been those "lean" years in which all I
could do was buy the various knife magazines and admire the work of others. Fortune, hard work, and those blessings which we can find if we look for, have brought me to a point in my life I can finally enjoy knifemaking the way I have always wanted to.
Fourth, and last, I'd like to post a link to one of your pages for others who may not have had the privilege to visit one of, IMO, the best pages on your website. Many would envy the obviously special relationship you shared with your Dad:
