FusionKraft™ surgical instruments are available in several materials including stainless teel, tungsten carbide, titanium, Diamond and UltraEdge. Stainless steel is a popular choice, but for your research another material may be a better option. Tungsten Carbide scissors last almost two times longer than stainless steel. Titanium is over 40% lighter than equivalent stainless steel instruments, with better flexibility and strength. Titanium is also 100% non-magnetic.
