2-Point Utility Blade for SK Series

Olfa HOB-2/5 blades fit SK-4, SK-9 and UTC-1 cutters with a hook-tip profile. Each pack supplies five carbon-steel blades for tradespeople who need quick changes on site. The straight edge suits general-purpose slicing through packaging, drywall paper and similar materials.

Consistent edge retention through repeated cuts

Carbon steel holds its sharpness across long scoring runs without the rapid dulling seen in softer metals. A 0.024 in thickness resists flex when pressure is applied along the 2 17/32 in length. The hook tip engages material cleanly at the start of each stroke.

Direct replacement for worn SK-series blades

Swapping dull blades restores original cutting feel without buying a new knife. The upgrade is worth it when the old edge tears rather than slices, or when the tip no longer catches sheet goods. Five-blade packs keep a spare ready in the pouch.

Questions about this item

How much heat does the carbon-steel blade generate during continuous cutting?

The blade itself produces no heat; any warmth comes from friction in the material being cut, not from the 0.024 in thick steel.

Which handle models accept this 21/32 in wide, 2 17/32 in long blade?

It fits Olfa SK-4, SK-9 and UTC-1 series knives, matching Grainger part numbers 4ETV7, 5LC46 and 6ZTJ6.

Will the hook-tip design work with older Olfa cutters that use straight blades?

Yes — the blade length, width and thickness match the SK-4, SK-9 and UTC-1 series, so it drops into those handles without modification.
