I was at a local knife store and was browsing over the Buck knives when I saw a fairly large folder with double, slanted, stainless steel bolsters. It had wood handles, was a lockback and the blade was at least 3" in length. Didn't do more than glance at it but I can't seem to find any thing larger than the 501 Squire with a 2.75" blade. The blade may have been longer than 3" on the one I saw. What is the name for this knife. Is this the Duke?
