I agree with Dennis. I have a guy helping me who has worked in forestry for 30 years. He has kevlar trousers, a chain mail vest, protective gloves, a helmet with metal grill visor - and he spends £500 on his chainsaws, and maintains them properly. They terrify me to death! I suppose the same could be said of kitchen knives - should they only be bought by chefs - but I think it would be easier to have a bad accident with chainsaw rather than a knife
