Cardboard that arrived at home. What do you use to open it?
The cardboard side has been devised, and the number of items that can be opened without tools has increased, but when the tape is peeled off, the amount of garbage increases.
I think there are many people who open it with a cutter.
In my case, I collect cardboard boxes for collection near the entrance, so I want to open them as close as possible.
However, I feel that it is a little out of place to put a cutter at the entrance, and I also feel that the mini cutter for unpacking on the street is not easy to use and sharp.
Therefore, I would like to introduce RovyVon's "Utility U4", which has a high design and sharpness.
"RovyVon U4" is a metal carabiner. At first glance, it looks heavy, but since it is made of titanium, you will be surprised at its lightness when you hold it in your hand.
16g in numerical value.
The carabiner bar has a wide shape that is easy to push with your fingers, and the hooks are doubled, so the function as a carabiner is perfect.
The folding microknife built into the side is a feature of this item.
It uses a replacement blade for medical scalpels and has the highest sharpness.
Since it is a very hard metal for blades, it cannot be re-sharpened, but you can get a replacement blade (Feather No. 11) for less than 100 yen per piece.
There are many multi-tools with built-in knives, but the characteristic feature of this "RovyVon U4" is the lock at a right angle.
At the 0 degree, 90 degree, and 180 degree positions, the lock is applied using the bending of titanium.
This solid 90 degree lock function is very compatible with unpacking, and you can unpack smoothly by cutting from the back to the front.
Since it is originally a carabiner, it doesn't feel strange even at the entrance, and you can hang it on a hook, so you don't have to worry about storing it.
It is a tool that enhances the convenience of the entrance space.
