High carbon stainless steal is more durable. It can withstand the wear and tear of meat cutting and boning. It can tolerate the high heat of the dishwasher and they last forever. The cost of the material is also a factor.
High-carbon stainless steel holds an edge well and is resistant to rust. It will stay sharp between tunings and can be put in a dishwasher or sterilizing solution without becoming corroded.
