Hi, I bought this knife not long after moving out of the parents. It would be more than 30 years old. The steel is very hard and makes a high pitch ping sound when flicked with a fingernail. Just interested to know if anyone would know the hardness of this knife.
it's not really a kitchen knife but it has only ever been used as one
