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

0.6mm Thickness for Durability. Nice Case
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!

Get these for your NK box cutter
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.

Meant for Otacle Utility
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!
