Utility Knife Test, Which Blade Is The Best?

Utility knife test, which blade is the best?

The Project Farm is a YouTube channel that tests all sorts of things like oils, drill bits, batteries, etc. In the video linked below he did a test of utility knife blades that I found interesting. He tries to develop appropriate testing methods and this one looks pretty gapped to me.

From time to time I read posts requesting various knife makers to develop some sort of utility knife/blade. The video may give some insights as why that may or may not be a good idea.

I did not put this in the Utility Knife section because it relates to sharpness testing, Moderator(s) feel free to move it if there is a more appropriate location.

Depends on what one is cutting. Boxes ? Roofing tiles ?
For me it is double wall corrugated cardboard. Five feet long three feet high.
For that it is the Stanley Classic Box Knife Blade.
Why ?
It is 0.4mm thick ! ! ! !
Thin cuts ESPECIALLY when it comes to cutting cardboard.
I've tired everything else.
Also I'm not a fan of toothy for cardboard. Tried it.
Went back to polished. Polished slips through the cardboard easier.
Also with toothy blades I would end up with paper fibers in the scratch pattern and on the edge. That tells me there is more drag there while it is cutting as well.

I reprofile, nock the corners off the factory grind, call that convex if you must.
I touch up my box knife once it is convexed and polished rather than replace blades .
Candle wax on the whole sides of the blade is the secret "racing" ingredient.
Sure . . . I have a pile of box knives; some with thicker blades, some with "carbide" blades.

Give me the Good Old classic (very thin) Stanley blade.

I got obsessed with box knives a few years ago. I have more than these but this is a good cross section.



I find all I really need for boxes are these little dudes. And since they are so pocket friendly I always have one or two on me. The top one has the "racing" Stanley Classic 0.4mm blade. Note that the blade is shorter. Takes a swipe or two with a diamond file to get it to fit in this holder.
