Some Surpises Cutting Cardboard w/ the Delica

I had S30V chip cutting cardboard but some guy here on BF said he didn't believe my story of killer cardboard. Well here's more proof cardboard can chip steel.
 
If you say so. Because if you ask me, any time I have to use a box cutter, I think, "Damn, I could have been using my knife for this..."

Any time I have to spread peanut butter on a sandwich using a butter knife, I think, "Damn, I could have been using my 24 inch Martindale machete for this.."
 
well boys looks like the discussion is going off hill, we wo'nt get anywhere intelligent with this direction. me2 i'll try to give you a composition of the cardboard if it's relevent. i know spelling is bad but i'm still moving in the right direction.
 
And if you cut up boxes for a living you use a boxcutter. It's the right knife for the job.

I used to work at a big orange hardware store, and yes, you were issued and required to use a box cutter. :(:mad: However, given the choice, it is much more fun using my knives, to cut cardboard and break them down. As a suburban domesticated knife wielding survivalist, cardboard is a frequent foe of mine. ;)

Reports cj!!!! :D

You're seriously trying to equate using a pocket knife for box-cutting to spreading peanut butter with a machete?

The last time I checked in most warehouses the so called box cutters were dull as a butter knife and the general term used to refer to them in the industry is 'finger cutters'.

I would rather use a SHARP tool (my knife) than some pice o junk issued box(finger) cutter.
 
I'm having the worst trouble with my Delica 4, I CANNOT get it sharp to save my life!!!!!!!! I have a sharpmaker and a few other diamond sharpeners but NO LUCK!!!!! I don't get to EDC it anymore for that reason, Don't get me wrong I LOVE the delica but it should be easier to sharpen than this, I have other VG10 spydies that I can get wicked sharp..
 
They do make box cutters for a reason.

Nice way to get started on bladeforums. We're interested in knives. That should be obvious. Whether or not to use a boxcutter isn't the question here.

They sure do. So people not interested enough in knives to join a knife forum will have a way to cut their cardboard without borrowing our knives and chipping the edges. They make pencil sharpeners, eyebrow trimmers, nail clippers, nail cleaners, paper cutters, scrapers, awls, sheet rock saws, string cutters, letter openers, pruning shears, can openers, kubotans, paper clips, book markers, pin gauges, paper weights, and scissors for a reason too. So people too cheap to spend a little on a good knife have something to do with their money and a reason to carry a fanny pack/man purse/duffel bag all the time.

Seriously, I really think it has to do with the scraping of steel pipe I did before. I'm sure I've broken down boxes with this knife before and never had a problem. I'll give it a good sharpening this weekend and see if it keeps happening. Probably raise a burr and cut it off a couple of times, then try on some other cardboard.
 
My wife cuts carboard every day, all day long. However, they are only allowed to carry box cutters.

I have cut a lot of all kinds of Boxes with my old Delica but it was a spyderedge.
I have a old S&W that has cut a ton of boxes, never any chipping. I don't really like cuting the stuff with a good knife. Call me a sissy.:D

You might try convxexing the edge. That should help with the chipping. IMO
 
Come to think of it, I did have a convex edge on it for a while. Once I get some control over the angles maybe I'll go back to sharpening it on the belt sander. Actually, I'm pretty sure I will. I just want a nice convex, polished edge at 10 degrees, which will then allow effortless sharpening touch ups at slightly higher angles. You could consider it convex now I suppose. I use the same technique as knifenut sometimes, by sharpening on both strokes and not removing the knife from the stone. This gives a slightly convex edge, about the same as sandpaper on leather. The chipping is only as deep as the 20 degree Sharpmaker microbevels.

You might like to get a system like the DMT Aligner. Use it as your training wheels until you learn how to do it by hand on benchstones. Lately I've been working with my freehand sharpening, and I am in love with my new skill :D

This is a rare phenomenon but it's not unheard of. I gifted a couple of SS Delicas back a few years ago to a couple of co-workers. Exact same model, both of them have AUS-6 blade steel. One of them doesn't hold an edge very well and wouldn't rust if you submerged it in battery acid. The other one holds an edge really well but the dude is constantly wiping little rust stains off the blade. Maybe you got a bum blade. :cool:
 
What, so that I can do nothing with my $80 Stretch?

We buy knives to use em. We buy sharpeners to sharpen them.

...exactly! :thumbup:

but some do buy knives to stare at them lovingly and use them only to flick them open and close...
 
Not saying this is the case here but it has been known to happen.

Because production knives are sharpened on a belt or wheel, it can cause overheating of the edge = chipping on use. After you reshape and resharpen the edge by hand, you get back to the "good steel" and this will hold its edge a lot better.

For cutting heaps of cardboard I actually prefer something like BRKT's T.U.S.K. - but not all workplaces will allow a fixed blade. Depth of cut is easily controlled by choking up on the blade and unlike boxcutters, there's plenty of blade for cutting rope and cord - and it's tough enough to handle plastic
 
Stores requiring boxcutters and not allowing simple pocket knives? Where were the bosses on 9/11? You can hijack multiple aircraft with those kind of things. They are sharp. If some disgruntled worker at the local hardware store goes postal, I'd rather take my chanes with their POS model Gerber that is dull as butter because it has never been sharpened than arming them with a boxcutter w' a new razor.

...acidic sweat?

Cardboard does a number on my edges too. Could be my sharpening, could be the material. But seeing as I've heard recommendations before to strop on cardboard (unloaded) over at the maintenance subforum, I'd guess that cardboard contains abrasives of some sort.
