Well Ive enjoyed your comments for sure.
The knife is a genuine 112 , it is mine and was part of a limited get yourself out of trouble kit at the bottom of an 80 litre backpack. The tins belonged to one of two other climbers we found who had had an accident and had lost one of their sacks over the edge, hence we came across 2 guys, one rucksack, a good selection of ice axes (no shovels, earth moving JCB's or sticks of dynamite!), one of gods blizzards and after we separated to shelter into 2 ice caves tgat we excavated, the temperature was -20 based on meteorological reports after we got down. At about 03:00 in the morning it is damned cold and we needed food. The chaps I had found had Heinz beans and a supply of chocolate. I had foods that needed hot water and we went for the easy option, my knife, their beans. And the chocolate of course. Hence, one destroyed blade which is where this all began.... if any of you found a rucksack abandoned on the Matterhorn, you will find a fully functioning can opener in it.
