I suppose the reason a steel like this is used is that it's cheap. Hobby knife blades are meant to be disposable. They're definitely carbon steel as they do corrode.
My intention is to develop a blade that will last, of course it's more expensive but it would dull, snap or lose shape much less often.
What makes L-6 and/or 15n20 suitable?
And are your thoughts of an alloy like tungsten or molybdenum, in the event that price was no object for this purpose? And can something like Maxamet be fitted to this purpose?
