Unique Hack Saw Blades

Stonger, Faster Cutting, Longer Lasting Blades

Starrett's revolutionary Bi-Metal Unique™ technology joins two strips of high speed steel wires to a backing steel in a solid phase, using the principle of solid-state diffusion bonding.

Bi-metal Unique is fundamentally different from traditional weld or laser bonding processes that rely on metal diffusion as the union agent at the interface.

Starrett's proprietary (patent pending) solid-state diffusion process generates 170% more weld contact area to significantly reduce
fracture and breakage at the HSS/backing material interface.

The result is a much stronger blade that lasts longer and cuts faster than competing premium products.

Starrett Bi-Metal Unique – The stronger, longer lasting,
faster cutting bi-metal blade.

The teeth develop a
groove after initial use, altering the blade area engaged in the cut for
Multi-Edge Performance

The Unique grooved tooth geometry produces dual chips that are easily removed from the cut. This is the Split-Chip Advantage
