Overview

GRAFF's listing describes this as an "8% Cobalt Premium Hacksaw Blade, 12 Inch, for Stainless," so it's positioned as a 12 inch, cobalt-content blade aimed at stainless steel cutting rather than a general-purpose blade. It's priced at $8.70.

It carries a 4.5 star rating across 330 reviews, with bought_last_month at 100, meeting ToolHandle's buyer-activity floor.

Beyond the cobalt content and length stated in the title, no separate teeth-per-inch or hardness spec is listed. Buyers wanting those numbers should check the Amazon listing directly.

Performance notes
