A little known fact is that cardboard boxes are very dense. This may sound a little funny but in a way its very obvious. We use cardboard boxes all the time and in many cases every day. Look in your pantry and you will see them every where and they are used many times in heavy applications. This is simply because of the density of cardboard and if you work in a factory or in packaging you may find yourself cutting lots of boxes every single day. This becomes a problem if you are using cheap knives. The problem is obvious if you are in the industry, and its because your knife is always dull. So how do you choose the proper knife to work in a factory?
The answer is complicated and yet simple. Stop buying the most inexpensive knife you see that looks cool. Yes, it may have a great looking design on the handle or blade, but most likely it is made from the lowest bidder and out of the least expensive materials. Instead look for a brand name that is known in the knife industry. Yes the knife industry, not the sporting goods industry. So this means you actually need to do a little research. Brands are not country of origan specific either. Some of the best knife brands come from China, because they use quality materials and craftsmanship. Look for brands like, Benchamde, Spyderco, We Knives. These are the most known brands in the knife industry and starting with a high quality brand means most likely you will be getting a better knife. Now the actual steel on the knife is important. It actually will be what determines how often you need to sharpen your knife if you do the same task each day.
Ask yourself an important question. Do I work in wet conditions. If the answer is yes, then you will most likely want a stainless steel. Now remember, all steel rusts. Stainless, means it stains less quickly or rusts less quickly than a normal carbon steel. There are more types of steel than I can count, but here are a few good ones to look for. If you need a good stainless steel, look for knives that are made in cpm s35vn, cpm154, or vg10.
These knives will cost more than your truck stop knives, but will be 10 to 20 times the quality. Which means they will be tougher and last longer at your normal cutting tasks. For Carbon steel look for, cpm 3v, m4, or m390. These steels are amazing for edge retention but will rust faster than your normal kitchen knife. So keep them dry and enjoy your knew experience of cutting boxes without sharpening your knife every other day.
