Ok so the rule is a bit Vague.

Hit anything hard enough it could break i guess.... Putting "MAY SHATTER" is a grey area..
Is Hardox a no then as a weapon ? What is Carbides spinning bar made of ?

I have access to Hi Impact IRON ORE Machine Strips, extremely hard wearing and impact resistant strips that are 1 inch wide and 10mm edge. IF they are strong enough for this application They "won't" shatter.. how can i prove this on inspection ? or does that not matter.


*********** ZEE RULE i am referring too.

12.4 Hardened Blades Commercially manufactured, hardened steel blades that may shatter are not allowed.
