It appears that Gingher may no longer make these blades, as I am not currently seeing them as being available from any of my sources. Gingher no longer makes rotary cutters, so it is entirely possible that they no longer make replacement blades, either. This makes me sad, as Gingher is my favorite rotary cutter and blade :(
This blade will fit any 45mm rotary cutter. It is in a touch-free cartridge, so there is no chance of accidentally cutting yourself when you change the blade.
