No, for serious office this cute dog is not really suitable. He's just too easy. You can not use it with one hand and really safe and stable, he is not. Thus the use is simply too time-consuming and annoying. I now have him on my private desk. To prevent my cats push him off the table and at the same time to facilitate the operation, I have the underside provided with double-sided tape and unceremoniously stuck him. It works.
The knife is pleasantly sharp. Toll I think the tape itself: It can be written on and stuck almost invisible. Practically, when something needs to be put together, where the splice should not be the focus. Inserting a new role is a little more tricky and requires tact.
