Best blades
The best blades for the best knife. Long lasting and very sharp.

Best blades on the planet
I never use any other blades. One downfall though, the silly plastic storage box needs a redesign in my opinion, really fiddly getting the bugger open. Maybe it's my fat fingers? Who knows, but I dislike it.

The daddy
The absolute champion of craft knives, Olfa should be way more popular than they are. Sharpest blades I've used bar none, make Irwin and Stanley blades seem like cheap cutlery. Good value price too, as these stay sharp for ages. The only downside is that they can snap quite easily if abused. That's not an Olfa problem though, that's a me problem.

Whilst slightly more expensive than the standard blade’s these are extremely sharp and so far have performed really well and maintaining their edge.

These blades are so sharp. You have to be careful not to cut yourself just putting them in the knife. I use the mainly for cutting. I never snag as long as you break them often enough.

These are the best blades I’ve ever used.
They stay sharp for a good time, they don’t drag (even wet wallpaper) I’m so happy that I found them.
