Hi Grant,

Thanks for the comprehensive response. Understood and I appreciate your point of view.

Time, Money and Design pending I could bring along a robot with circular saw discs as weapons if you wish to do some tests. Although I would say I'd expect such blades to instantly fail and shatter against metal so wouldn't expect anyone to use them in that context from a design and safety perspective. Against wood though it may be a different story, so if you'd like to do some controlled tests against that I'd be up for it.

ps. I never meant to, nor do I want to bring anyone's safety into question so glad we got this sorted.
