	I should have further qualified that with "if you want 
	convenience".

	Their lack of hot hardness and general low grade of heat 
	tolerance will demand you work differently, taking care 
	not to draw the temper too much, rendering the tool useless.
	Smiths used plain carbon steel for centuries and got the 
	work done.  I did not mean to imply that the steels you 
	listed were of zero value.  I meant to say that the high 
	alloy, heat tolerant steels allow you to work more conveniently. 
	My apologies for speaking neglectfully.
