When I originally acquired this knife I thought it was a bird's head version of a 140 but now I'm not so sure it's not a 146. I could be missing something obvious, but I can't find a difference in the descriptions of the two patterns. At the time I was hunting for bear's head knives, so I may have just had 140/141 on the brain. Can anyone tell me if there is a difference between a 140 and a 146? Thanks.
