Nicolai Diamant now offers sets with fewer tools needed. Even with less tools, this sequence provides quick results and high-quality edges. These sets consist of 4 diamonds + 1 polisher. First, the 4 diamond tools run at a higher speed to create a beautiful edge in a timely manner. Next, the ultra-fine 5th metal is ran to eliminate lines on the profiles edge. Finally, the polisher runs along to create a mirror-like finish. On top of the fast cutting and speedy results, Nicolai Diamant has also made their tools eco-friendly with no cobalt and no nickel in the bond.
