I kinda want to pick up a gerber flik since the sliding head looks pretty cool. But on another forum someone mentioned that gerber multitools use sintered steel and is more fragile than say leatherman. I don't know jack about anything metallurgy, so does anyone know if it's true?
Cold powdered metal (along with a small amount of binder) is compressed under 10's or 100's of tons of pressure in a powdered metal press. The resulting "green" part is checked (usually by weighing it) then heated in a sintering furnace to burn out all of the binder and fuse the powdered metal together. The resulting near net-shape part may have secondary forging or machining operations done to it after sintering. These parts can be made very strong - many gears are made this way, as well as connecting rods for high-performance engines.
