Alternating layers - How it works:

Side view

Performance test results show dramatic increase

in both cutting speed and tool life.

Ehwa has been researching patterned blades since the1990s.

However, a straightforward pattern is only random

distribution at its best.

EHWA DIAMOND INDUSTRIAL CO., LTD.

Universal

Revolutionary dual-diamond concentrated segmented blade technology delivers

a precise cut in one smooth stroke. The segmented blade cutting edges feature

alternating mirrored angle of attack for faster opening speed and longer blade life.
