So, how is it that these two knives are similar?  They might be close to the same size, but I'd venture to say that the Buck 124 has less mass.  If I were to pick one Buck knife for the trek around humid environments, it would most certainly be the 124.  I have found that the handle is just slightly big for my hands.  What I do like about the knife is the the solid full tang construction.  I believe this to be the sole full tang offering within the current Buck line, but I may be incorrect.
The Wauseon knife in the photo (nice pic by any stroke of the imagination) is a tougher, more durable blade if you are going to beat on it like a rented mule.  If you have any type of prying on the agenda, feel free to appropriate Jerry's blade in such a role.  My take is that these are two, very different knives with very distinct purposes.  Both are solid choices.  I still have an exceedingly well used Nemo that has been to Hades and back, a testimony to the longevity of the 440 ilk pushed by the now ancient El Cajon facility.
