OLFA Utility Knives 5003 Editorial Review
If you're looking for a knife that can cut through a variety of materials, the OLFA 18mm Heavy-Duty Utility Knife L-1 is a great option. It's been used to cut everything from paper and foam board to building materials like fiberglass insulation and even roofing shingles. However, it may not be strong enough for cutting through 2" insulation board. The knife uses 18mm blades (part number LB-10B snap off blade) and does not have storage for spare blades. The blade is 1-centimeter long. In terms of customer reviews, some users criticized the fragility of the blade, while others praised its ease of use and durability. The knife has a steel blade guide and locking wheel for added safety and durability. It also has an additional protective bump to ensure the blade stays in place during use. However, one user noted that the one included blade isn't very sharp. Overall, the OLFA 18mm Heavy-Duty Utility Knife L-1 seems to be a reliable option for cutting various materials. While there were a few criticisms of fragility, many users praised its durability and ease of use.
