well i knew that.. but i decided id hold the avacardo while i was doing it... tapped with knife once.. tried to twist.. no stone.
tapped again.. knife went through stone, flesh, and skin.. and then down to the bone on my left index

got a lovely scar.. and nearly fainted.
ran into dining room crying and holding my finger while dad was in the conservtry not being able to hear a word i said.. so i was stood boucning around infront of the glass door for 5 mins before he realised summit was up lol
if i had never gone to catering college.. or become a chef.. i never would have spent hundreds of pounds on big expensive posh knifes that have the ability to nearly take my finger off.
hindsight is a wonderfull thing! lol
