Buying Guide

Choose the right blade profile

Match point style and edge geometry to the task—fine-point for precision cutting, hook or roofing blades for tear-out, and straight edges for general slicing

Match blade size and fit

Confirm blade length and mounting type (18mm, 25mm, single-edge, snap-off) to ensure compatibility with your cutter or tool

Prioritize blade material

Look for SK2, high-carbon, tungsten, or hardened tool steels for longer edge retention and abrasion resistance

Consider blade count vs. cost

Higher-count packs reduce per-blade cost but verify packaging and storage convenience for frequent use

Assess task-specific coatings and formats

Snap-off blades offer quick fresh edges, while replaceable razor or single-edge blades suit scraping and box cutting
