So much effort just to find out if it’s legal or not aii. Play with it until you’re told not to💀

Would you be able to manufacture and produce stick testing kits? A ring and cathedral?

Very confusing 'explanation' of the maximum permitted bow. You made it appear that the point of the 'cathedral' HAD to fit beneath the flat of the stick at the point of maximum distance from the flat measuring surface.- which just ain't so. There should be no gap between the point of the 'cathedral' and the face of the stick at the maximum distance. If the point of the 'cathedral' will not fit between the flat surface and the flat face of the stick that is not a problem at all. You omitted to mention the maximum height of the head part (the upturn of toe or hook) and made no reference to the plane of the face of the stick-head compared to the plane of the flat of the flat part of shaft above the stick-head - they should be in the same plane. The stick you were measuring appeared to be 'off' in this regard. There is also a limit of 4mm for deviation of flat surface across the plane of a stick-head. On the point of deviation, you neglected to mention the 20mm "permitted deviation" allowed in the 'straightness' of a hockey stick handle. This should not be confused with permitted bow or with the rake of a stick (the curvature previously achieved by the angle of join between the head and handle when the handle was spliced to the head part - which previously defined the head part of a hockey stick (that changed in 2004). Rake gives a bow to the heel edge of a stick placing the stick-head slightly under the hands - because the last thing wanted by player is a stick that curves in the opposite way. The shape and configuration of a hockey stick is a lot more subtle and complicated than you have suggested. I provide a link to an article suggesting an update to the Stick Diagram, which the FIH Rules Committee and the FIH Equipment Committee have been ignoring for more than twenty years. wordpress.com/post/martinzigzag.com/11744

Can someone explain to me why is the stick only the right hand and not other way around? I tried to use it but I almost crippled myself, thanks :)
