What are the regulations for floorball blades?

The International Floorball Federation (IFF) determines the regulations for floorball blades worldwide. The same regulations apply to the Swedish Floorball Federation when playing in Sweden. All equipment approved by the IFF must be tested and verified by SP, the Swedish Technical Research Institute.
For a floorball blade to be approved, it must meet the regulations established by the IFF. Most of the rules concern various measurements. The primary purpose of these regulations is to ensure that the equipment used in floorball does not cause harm to players.
It is permissible to adjust the hook on your blade as long as you stay within the hook regulations. However, other modifications to the blade are not allowed. You cannot remove ribs, cut out filled areas, or spray-paint the blade in a different color.
It is acceptable to apply tape around the joint between the blade shaft and the stick. However, the tape should not extend more than 1 cm onto the blade neck. Also, keep in mind that many sticks have their approval markings near the blade, so do not tape over them.
