Ingco HUKB611 Utility Knife Blades 61x19mm, 10-Piece SK5 Set

Our review

This is a ten-piece pack of replacement utility knife blades from Ingco, sized 61 by 19 millimetres and made from SK5 steel. It suits anyone who already owns a standard utility knife and goes through blades regularly: box cutting, carpet trimming, plastic sheeting, cardboard breakdown, and general workshop or site work. Because the blades are consumables, the practical question is not whether they cut but whether they fit your handle and hold an edge long enough to be worth buying in tens. Before ordering, check that your knife takes the 61x19mm blade format, since utility knives come in a few sizes and a mismatched blade is useless. Compare the SK5 steel against generic carbon blades, which often dull faster, and against snap-off blade knives, which suit lighter tasks but cannot match a fixed blade for rigidity. Ten pieces also means fewer interruptions mid-job, though you should still store them somewhere dry and out of reach of children. If you want a straightforward refill pack rather than a new knife, this set is available on Sokonia.
