Micro Precision Cutters - curved blade Razor sharp! The action springs back to the open position so ideal for cutting those threads that you cannot normally get to with your standard scissors. Good for cutting small pieces for placement on paper craft projects. Absolutely idea for cutting excess rigging material once the glue has dried - because of the curved blade it is easy to get right up close to the turnbuckles (yeah, we all use scale turnbuckles on our model bi-planes - right!). This surgical scissor is so precise that they are sharpened under a microscope.
