Heavy-duty staplers mean that the teachers can work efficiently and considerably fast speed. However, since heavy-duty staplers are weightier than others, teachers would be a little reluctant while using them around children. This makes perfect sense as the security of children comes first. If you are looking after a class of younger children, going with a heavy-duty stapler will not be a good option. On the other hand, if you are teaching older students, you can consider going with the latter. Also, with older students, a heavy-duty stapler is more suitable as it will allow you to work fast.
