Detailed Review

The OLFA 18mm Heavy-Duty Snap-Off Blades (LB-10B) provide replacement cutting edges for contractors, industrial workers, and everyday users tackling tough materials. Designed to keep work moving without frequent full-blade swaps, this refill pack supplies 10 individual blades that fit into compatible utility handles.

Crafted from Japanese tool grade steel, these blades focus on edge retention and clean precision. Each individual blade features 8 snap-off segments, providing a total of 80 sharp edges per 10-pack. When an edge wears down from repeated cutting, you simply snap off the dull segment to expose a fresh, sharp point immediately.

These heavy-duty blades are built to handle dense materials such as drywall, roofing, flooring, and rubber. While engineered for optimal performance when paired with OLFA 18mm handles, they are universally sized to work in most standard 18mm utility knife bodies.

As snap-off blades, they are designed specifically for 18mm handles and will not fit smaller 9mm craft knives or standard trapezoid utility knives. Users looking for larger or smaller quantities should note that OLFA also offers alternative pack sizes of 5, 50, or 100 blades.

Verdict: The OLFA LB-10B 10-pack is an ideal refill choice for anyone needing durable, steel blades for heavy construction, flooring, or industrial slicing tasks. It delivers dependable sharpness and convenient snap-off segments to keep your projects moving without downtime.
