Ronix Utility Knife

Ronix snap-off blade knives. Snap the dull segment off with pliers and you have a fresh edge — never snap one with your fingers.

• Check before ordering: 9 mm is for card, film and light work; 18 mm is the general-purpose size; the 19 mm heavy-duty has a metal body and a screw lock for cutting insulation board and carpet all day. Two 18 mm lines sit here at €1.06 and €1.20 — worth checking on the shelf whether they are actually the same knife under two codes.
