Some people have mentioned the safety of our Metalica because the blade part is exposed. If you take care of it carefully, it is hard to get injured with the edge of both ends, we estimate. Even so, we have to value those voices from the users’ side. After we considered how to materialize those requests, we succeeded in covering the sharp parts.

As you might have realized, once we cover both ends of the blade, you cannot use those parts for trimming(cutting).
Yes, it’s true but this is the trade-off relationship between practical and safety.
Protecting employees from external wounds is one of the most important precautions of your organization.
If you don’t need to worry about unexpected injury, you may say this is an “easy-to-use” knife.
