What material(s) do you find yourself cutting through, into, and or around that you know lead to a dull edge the fastest? Obviously there are things a blade isn't meant to cut. I'm referring to the stuff that you know is within reason but you can't help but cringe at.

Vinyl is mine. I often have to trim, round off, and detail pieces of it for work. It eats up a sharp edge.
 
ductboard...aka fiberglass board. eats a sharp edge away in one cut basically. same here have to cut it for work.
 
It's been a long time since I've had to do it but carpet can be hell on blades. And it it's old it can be REALLY nasty. Ugh.
 
Cardboard. The worst thing I've ever had to cut was fiberglass insulation...itches something fierce too.

i roll in the stuff almost daily. i've become about immune from the itching, but i can still remember my early years with the stuff and coming out of attics after cutting old ductboard ductwork and as soon as the sweating stopped coming out of the attic the itching started something fierce. it is nasty stuff on blades and body parts without a doubt.
 
Definitely cardboard, I avoid cutting it whenever possible.

Actually, what's worse than that is cutting food on ceramic plates. Definite no no for me.
 
What wrong with cutting cardboard?

Mine is bone (fish) or anything hard thatll chip my knife.
 
Zip ties are bad, so it cardboard. Worst is sod and bags of dirt though.

Cardboard is full of impurities which cause micro-chipping. Doesn't matter what kind of steel you're using.

I think S110V will perform a bit differently than 8cr14MOV in cardboard. I don't really mind cutting cardboard with my knives; it is a task that has to be done and it gives me an excuse to sharpen my knives. I already carry 2-3 knives daily, I am not going to add a box cutter.
 
Drywalls and zip ties, oh and algeas as stupid as it sounds for most of them are corrosive
 
Those nylon straps that go around cardboard boxes. And any gummy tape like duck tape. And hidden staples in cardboard. I use my partially serrated BM mini-Barrage for most of these tasks as it rips through pretty much anything.

Another vote for cardboard. Also zip ties.

Cardboard for me as well, I find pliers or a pair of scissors work better for zip ties from my experience. I probably cut up over 100 zip ties and finally settled on my SAK scissors when I rebuilt my computer, though pliers worked better I just didn't have the room for it.
 
Ah nice to know!

Also ive chipped my yanagi on a lemon seed before, was one tough seed.
