50-Pack Utility Knife Blades, Titanium Fully Plated, Durable SK-2 Razor Blades for Utility Knife Box Cutter, Never Rust, Extra Durable

For the price, I can't complain. They hold their edge for a decent amount of work, but they do dull faster than more expensive blades. I use these to break down boxes and I usually buy packs from name brands. I notice I'm switching them out more often (feels like they last maybe 80% as long). That being said, considering how many you get for the price, the dollar per blade amount is better than buying 5 packs of name brands.

Let me start by saying that I use my utility knife daily, opening packages and boxes. Not hard use at all. These blades allow you to sharpen them as needed. When I notice it getting dull, I put it to a honing rod and its as good as new. I may never need to buy blades again. High quality product at a fair price.

These blades are significantly sharper than standard utility blades. I’ve been using one in my Milwaukee Fastback as my everyday pocket knife for the past two weeks, and it’s still holding an incredible edge. Even better, there's been no corrosion or grime buildup—still looks and performs like new. Highly recommend these for anyone using a utility knife for daily tasks. The only downside is the packaging—it comes in packs of ten with no easy way to dispense a single blade. A better dispenser would make this a perfect product.

Go for the gold! I give the gold ones 5 stars The black get 3 stars The black ones don’t stay sharp maybe stronger steel but are great at cutting

10 out of 10. Great product.

Extremely sharp and long lasting

Best box cutter blade I've ever used in fact I bought more very sharp

It's a cheap razor blade. Workpro sk5 for the same price but 100pc come hair popping sharp. These are not finished correctly and have a small bur; not hair popping. If that matters to you look elsewhere. Bought these for the rust prevention in a rainy work environment edc blade. If you don't mind the extra hassle, all it takes is a few passed on a strop for hair popping sharp. May seem dumb to strop a utility blade but so is buying dull blades.
