18mm snap-off blades, 50 to a box. Rigid steel segments for cutting insulation, plastic sheeting, and heavy liners: when the edge dulls, snap it and keep cutting.
Fits any standard 18mm snap-off knife. Eight points per blade, so one blade lasts a week of site work.
Eight snap-off segments per blade keep the edge fresh all week.
Rigid steel cuts dense material without wandering.
Fits any standard 18mm snap-off knife.
Snap a segment as soon as cuts start tearing; a dull blade needs force, and force is when blades slip. Snap with the knife's end cap or pliers, never fingers, and bin used segments in a rigid container.
18mm width suits standard snap-off knives only. Very fine cutting wants a scalpel or trimming blade, not a snap-off.
