Inexpensive, unused knives are great for breaking up cardboard boxes

[ditomura]

I’ve been using razor blade box cutters and pocket knives to break down cardboard boxes and they’ve been working good enough. I decided to use an unused, complimentary 7 inch Emeril Lagasse Wusthof knife. This worked so much better than everything else I’ve tried. It goes through the carboard much easier.

I used a Henckels 4 Star chef to break down a big box. It went fine until it found an unremoved staple for me.

In my reveries there must exist a Wunderstahl/acero brujo/kaijugami that encounters staples, nails etc. and keeps going, possibly even deburred by the experience.

I tried using a ryoba but it clogged in seconds.

I might could get one. Teeth are not like a wood saw at all.

About this item​

• [Japanese Versatile Box Cutter Knife] The CANARY cardboard cutter is the ultimate tool for cutting cardboard smoothly. The unique serrated blade is made of high-quality Japanese stainless steel and can easily cut through cardboard, packing tape, stretch wrap, shrink wrap, and banding. It is an ideal tool for opening packages from your daily online shopping, making cardboard cutouts, creating cardboard crafts, moving, and professional warehouse work.
• [Safe Blade Cover] It is small and has a blade cap, making it convenient to store or carry in your pocket. The rounded blade tip and micro saw teeth, designed specifically for cutting corrugated cardboard, make it safer than a general utility knife: It is designed to minimize the risk of injury when touching the blade edge. * Be sure to use the sheath when not in use, as an exposed blade can cause injury.
• [Non-Stick Teflon Finished Blade] The black blade has a high-grade fluorine coating. Even when cutting duct tape and packing tape, adhesive does not stick to the blade, maintaining its sharpness and making box opening tasks easy and enjoyable. If sticky material does adhere to the blade, it can be easily wiped off.
• [Lightweight BUT Heavy Duty] The blade is made of heavy-duty Japanese stainless steel. The fixed blade is securely integrated with the handle, so there is no need to worry about applying strong force, and it prevents foreign matter (like blade fragments) from remaining in the box. Although it is a small and light hand tool, it can also handle breaking down large amounts of cardboard.
• [PRODUCT INFORMATION] Blade: Japanese Stainless Steel (Non-Stick Black Fluorine Coated) / Handle: PP / Overall Length: 7.5" / Blade Length: 3" / Weight: 0.8 oz. / Made in Seki, Japan

For big piles of thick cardboard, e.g. something a TV or furniture came in, take it out to the yard and hose it down well. Let sit for 30 mins or so then just crumple up and toss in the recycle bin.
