For what it's worth. When I first started off I purchased a 1x30 and tried it for a few blades, but then dipped into the funds to get the 2x72. In retrospect I should have foregone the 1x30 and put that money into files, 1/2/3 blocks or other bench tools. I'd hold out for the 2x72. But that's just my opinion. Good luck and looking forward to seeing your work.
