OKNIFE Utility Knife Blades 10 Pack - Compatible with Otacle U1 & U1 Pro Series and Most Utility Knives, Ultra Sharp Durable SK2 Steel for Heavy-Duty Cutting Tasks

Great product and of course it's razor sharp

These fit the OKNIFE and are scary sharp. I think you could do minor surgery with these.

SK2 Steel is treated for exceptionally high hardness, around 65HRC! Therefore, I avoid gritty, rough use & focus more on precision slicing for long edge life. Grit or heavy duty use may cause edge chipping. To help stabilize the blade, they’re a bit thicker (0.60mm) vs. standard light duty blades(0.50mm). Very portable with the nice case & latching lid. Came well oiled & plenty sharp!

Just as advertised. Fit perfectly into my knife and are great quality.

Best blades you can get.

We have a cool NK folding box cutter. It was a gift from a connoisseur of fine knifes LOL. Once breaking the tip off the blade that came with it, we headed to Home Depot to get refills. Not so fast, turbo. The blades on the shelf do not have the little holes needed to line up properly. So we returned the ordinary blades and headed to Amazon for the more esoteric varieties. The hole pattern of these blades looked right, and they were. BTW, you’ll need a tiny torx pattern wrench, to open your knife. Hold it over a cloth, so the world’s tiniest screw won’t bounce away and disappear forever. So, awesome, we can use the knife all we want without treating it with kid gloves.

The blades are sharp and come direct from Olight. No complaints here! Great company. These should last you a while as I've cut through many boxes without even needing to flip the blade around yet, still on my first one!

They work like they’re intended. Nothing else will work either the knife do to the screw holes
