To ease the selection of a tool, we have classified them.

There are tools with low, medium and high effort. High effort means that the application of the tool takes a lot of preparation and is highly material-intensive.

The complexity (easy, medium, hard) describes whether a tool can be applied without training in advance or any in-depth explanation, i.e. without having heard of the tool before.

More complex tools are not that easily revealed to the user. Having in mind to give a try to a new tool? In this case, it is recommended to use the filtering function and choose tools with low complexity. Looking for a challenge? Come on and try some of the more complex tools.
