Upgrade your Knife Sharpening Tool!
thingiverse
Change the emery stones when you sharpen your knives, how long does it take :)\r\nYou can install four emery stones at once instead of one.\r\nYou can also set only three or two or even one stone here.\r\nI upgraded the standard Knife Sharpening tool purchased on AliExpress.\r\nYou can also improve any similar Knife sharpening tool that uses a metal rod with an 8 mm diameter.\r\nOne of the stops will need to be fixed on the rod, this requires a single screw M3 length of 15-20 mm with a hidden head.\r\nUpgrade your Knife Sharpening Tool!
