I wouldn't normally review something like this, but I felt this was warranted as it's been amazing. It's super sharp and stays sharp for a long time. I'm usually just cutting boxes and would normally need to snap off pieces of the blade to get a sharper edge at least once a month if not more depending on the box load. However, these blades have been fantastic and I've been still haven't had to so for 2 months already.
This is one of the sharpest, most durable, and high quality blades I've ever tried. I am going to come back to it for the rest of my life.
the blades that came with the knife were not covered with oil!
my bad for opening them 1.5 years after the purchase so I cant return them. they are covered with machine oil!! how can I cut open packages of food??!! #sad.
I use these for cutting insulation foam for hobby projects where clean straight cuts are vital. These are the best blades
