Maker of razor with unknown alloy (6)

'maker of razor' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'unknown alloy' is the wordplay.
I cannot quite understand how this works, but
'unknown' could be 'y' (algebra) and 'y' is present in the answer.
The remaining letters 'occam' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).

'with' acts as a link.

Can you help me to learn more?
