Den,

My understanding was that the Krebs "Fatman" was so called due to the width of the blade. There has always been a big difference of opinion on whether these were period produced or post-1945 as souvenirs for GIs. I can't say for certain except to say they are a variant that remains desirable to collectors. I would buy one of the price were right.
