Day 1 - Going to show one feature a day for a month on one of my favorite modified SAKs- this is a Victorinox CyberSwissChamp AVT. Large Blade - 2.7 inches long (6.8 cm), X55CrMo14 Steel, 56 HRC. Like to use it for food prep, emergency blade or as mirror on occasion. Easy to sharpen and extremely stain resistant. One of the many reasons I like Victorinox so much.
Day 3 - File - HRC in 60 range, great as a nail cleaner/file, and works really well as a file on soft metals, wood, plastic, etc.. or as a metal saw. Have to take care if you use it as a long #1 Phillips driver or to pry since it is hardened and can break or warp.
Day 2 - Small Blade - 1 & 5/8” (3.8 cm), same steel and HRC as main blade. I use this blade about 80% of the time and the large blade 20% of the time. Originally designated as a “ink eraser” and earning name “pen blade.” Way underrated, as it has a thinner spine, less width, providing better control when you carve or make precision cuts. This blade even provides less risk of damaging contents when you open packages.
Day 11 - Can Opener - Has 3 mm Flathead Driver, in-line #2 2D Phillips Driver, open square valves, great for scraping, removing SAK scales, light duty prying when you need a sharp edge to access, handy to remove wire handled or open cans off of a camp fire, or even pulling or pushing closed hot oven grates at home.
Multipurpose Hook...million and one uses.
