Edit > Knife to Knife 
This tool enables you to add a restriction of Knife to Knife type to the female profile of the currently selected stripper area/region.
Knife to Knife restrictions are placed as a lug, and the depth is always equal to the female offset; therefore they can be used for sheet registration.
Edit bar controls
Width 
This option allows you to explicitly override the width of the restriction as defined in the system settings.
Auto Infer 
If this option is checked, then the tool will check for the same configuration of entities and blocks as the picked entity in other parts of the stripper area/region, and automatically place restrictions here too.
These inferences will be linked so that editing one later will affect all of the inferences.
System Settings 
You can make a temporary override to the System settings currently being used by the Stripper Creator by changing the values shown in the Stripper System Settings form.
Area 
You can make a temporary override to the area helper settings currently being used by the Stripper Creator by changing the values shown in the Area Helper form. A defined area can then be displayed on the cursor to help gauge the size of any restrictions added.
Angled 
If this option is checked, any editing of a selected component using the drag handles will allow changes to the angle of the component. Otherwise, the angle of the component remains fixed.
How to use the tool
Pick a point on the profile of the selected stripper area/region to add a new restriction.
Existing components and restrictions within a selected region will be marked with drag handles of different shapes. These can be edited in the same way as the Select 
tool, without the need to explicitly start that tool.
