Utility Knife Blades 100mm Carbon Steel Replacement Cutter Pack

Stock sharp replacements with these 100mm × 18mm carbon steel utility knife blades for everyday cutting and carving. Black finish blades snap into standard utility knives for office, craft, and DIY jobs.

Choose pack sizes from 10 to 100 pieces so you can refill the knife you already own instead of buying a new handle. Hardened carbon steel edges stay useful through cardboard, tape, and light materials cutting.

Ideal for warehouses, makers, and handymen who go through blades quickly. Keep a spare pack in the toolbox so dull edges never slow a job.

A simple, affordable cutter-blade refill for shops and home workshops. Pick the count that matches your burn rate and swap blades the moment they dull.
