A word from the inventor:
I hand-made my first pair of “Lumsden BioScissors” out of desperation. There was no scissor on the market small enough to make the precise clean cuts I wanted in the very small and slippery objects I was operating on. The customary tool for this purpose was a round-section needle of glass or flame-sharpened tungsten wire – which tear rather than cut at the fine level, and which stretch the tissue and leave it with ragged edges. For microsurgery a tool with opposing cutting edges would be so much more satisfactory. I fashioned the first pair from commercially available suture-tying forceps in stainless steel, 
grinding away the sides of the opposing platform tips by hand to generate cutting edges. Even though the execution was less than perfect, they worked pretty well – though it was impossible to make two pairs exactly the same and stainless steel never keeps its initial sharpness. Now, with a production series made from purpose-designed forged titanium blanks, with precision-ground cutting edges and light spring action, we have achieved repeatability of cutting action and enduring sharpness of the cutting edges in a very high quality instrument that will see years of service.
Unique pincer cutting action. Unlike a conventional scissor, which cuts from the pivot point forward toward the tip, the Lumsden BioScissor cuts from the tip backwards, allowing the cut to commence from the first point of contact. This means that the scissor essentially doubles as a forcep, fixing the tissue as it cuts rather than pushing it away.
No pivot. The overlap and cutting angle of the blades is set by precision grinding at manufacture and maintained by the lateral rigidity of the spring handles.
Minute cutting edges. Less invasive of the tissue and less obstructive of the field of view down the stereomicroscope.
All titanium construction. Light, strong and hard, ensuring long-term sharpness, autoclavable, rust-proof, non-magnetic and with non-reflective anodised finish.
