The reason the "soldier" model, and subsequently the pioneer, is heavier duty is because they are the offspring of the original "soldier's model" knives actually issued to Swiss Army personnel. These fighters didn't need all the bells and whistles but a good blade, bottle and can openers, and an awl. The other models with the red celador (sp) handles are technically "officer's models". This kind of irritates me since the implication is that officers needed the corkscrews for "our evening wine and cheese parties" during combat! Nevertheless, I have the soldiers and pioneer models ready for military duty and the fieldmaster for everyday use.

PS: Since 1993 the US bound soldiers model has no hollow rivet to pass a lanyard through. Lots of these are lost since there is no way to secure it. Hence, the Pioneer is my favorite Alox handle model (although I did run into a closeout off of a display board a couple of years ago of a 1993 model --the date is stamped on the blade tang for soldiers models. A good find.
