When I started on the Northern Tier in 2012, I had not cycled on a self-supported trip before. I did not have a stove. I used it to open cans of tuna fish. I am thankful for the wide availability of tuna in foil packets and many options not in a can. On my next tour I used the opener on my pocket knife. After that, I haven’t carried any cans. At 6.4 ounces, it was a heavy luxury for limited use.
My packing list is much more refined today, yet it still is not as light as I would like it to be. It still is not an ultra light packing list.
