hi - i just bought a new old stock victorinox knife , i think from the 70's or early 80's - regular large size, red plastic handles, has a different style swiss cross logo and does not have a tweezers or toothpick, and the awl/punch/reamer does not have a hole in it - the closest modern model i can compare it to is a huntsman , but without the parcel hook - my question is about the liners , they seem to be aluminum - are the newer ones steel or aluminum ? - it also feels a little lighter than i think it should - i do not have any regular red plastic handled victorinox knives to compare it to - the alox soldier model is the only other victorinox i have - so, does anyone know if they always used aluminum ? or do they use steel now? - could anyone tell me the years they made them without the tweezers and toothpick and with a different style cross logo ?( i am guessing at the age based on things i have seen and the packaging ) - any help would be great - thanks - marc
