You making a career of it or just  a one or two?   Therein lies the 
answer.   Unless you just have a penchant for slick looking tiny planes. 
Then that's your answer.

I made my own planes. Needed like two.  Didn't use 'em enough to justify 
specialty irons ( not that there were any available in the 1970s),  
Hardened the edges by hammering  the steel along the edge much like one 
might with a scythe.
