cardboard knife?

Have you guys ever seen how a Kershaw Needs Works just plows through miles of carboard and touchs up extremely fast due to its straight blade configuration?

If you answer NO, you haven't lived yet :D
 
Looking to change up my knife for a NW actually. Looks like a great choice and comfy handle too.
 
so the d2 has better edge retention.
what about the durability of a convex edge vs the ease of sharpening (maintaining/steeling) a standard v grind?

I find nothing difficult about maintaining a convex edge. In fact, I find it easier to maintain, because you don't have to be as fussy about angles. I have found it to be a usefull skill. Also, you can still touch up just the edge with a stone or ceramic rod, lightly, and stay screaming sharp.
 
Thank you all very much for your valuable insights and opinions. I appreciate it greatly.
 
uncouth,

I work in a corrugated manufacturing company and I deal with the material all day long. Like many people mentioned, your regular old run of the mill stanley box cutter will do a great job. I have tried the folding box cutters and did not care for them much. Most are built to cheap, just my opinion. I also own the small Gerber box cutter. It is a handy tool for light jobs but if you are cutting triplewall all day you will notice that it really digs into you hand after a while, not great for heavy duty.

Now if your like me and like to use your EDC, partly to see how the steel holds up and how the egros feel and also cause heck, it's fun....hey we're knife nuts....right? :D

I found that a knife that does a great job is a Benchmade Griptilian with the sheepsfoot blade. The 154 CM on mine just seems to hold up for a great time. The hollow grind doesn't bind up much and it just seems to cut super clean. I suggest the sheepsfoot blade because the spear point is flat ground and the grind is just much thicker causing it to wedge when you are trying to cut.

Let us know what you decide. Pics would be great :D

Best,
Bravo
 
The Stanley retractable blade knives are cheap and ideal. They make a nice, inexpensive one that is smaller than they common Model 99. Ergonomics on these type OTFs are usually pretty good for hard work. If you like sharpening, there's no rule saying you can't sharpen utility knife blades.
 
well after all the input i think i'm going to try and convex the edge of my opinel, it already has the convex blade may as well use that to learn to sharpen convex edges on. although i did find a good deal on the crkt edgie that radeo mentioned, i'm sure for me that will only be used once or twice, it seems more like a novelty item. if the convexing of the opinel goes well, then i'll probly try and find a traditional folder in the d2 when i can find the moola.
 
Having had to deal with cutting a lot of cardboard in a number of jobs in my life here are a few knives that work great.

+1 - I also find convex not just better - it's the best for GP/utility use when it comes to sharpness; sharpening; edge retention. You can strop a convex edge on your belt, sheath or even a piece of cardboard should you need to give it a quick "touchup" and not worry about having to maintain a specific angle.

You can pick up an amazing Spyderco Stretch 2 in FRN and ZDP-189. I would go with that if I had a lot of cardboard to chew up.

When sharpened right I've used mine to cut dozens of yards of cardboard without any noticeable edge loss/damage. It's a nice thin grind that combined with the handle is a dream to use. I despise the folding utility knives and small box cutter type blades. They're generally very unergonomic and don't really offer very good performance.

A nice folder with proper technique (hold the blade 45 degrees to the cardboard, not 90) works much, much better.
 
I work in shipping and cut a lot of cardboard every day. I use an Opinel #7 Carbon and give it a few swipes on a DMT stone every morning to keep it razor sharp.
I use a Mini-Grip for general tasks around the warehouse, but the Opinel blows it away when it comes to pure cutting efficiency.
 
Anything thin and comfortable will do. High wear resistant steels help, but a knife with thin geometry (Like the Opinels tapedeck mentioned) will slice for a long time, even if they aren't a super wear resistant steel.

I really like my Spyderco Swick for cardboard. I reprofiled it to about 10 degrees per side and gave it a highly polished edge.
