Support BladeForums! Paid memberships don't see ads! I have an aluminium machete blank that was made to test the fit of the prototype CNC handle and it's scary light and fast. However milling in a dovetail way and attaching a steel edge would not be practical as the aluminum would break at the joint with hard chopping. It would also cost a lot to do and there would be issues with the edge coming loose. What I can do is offer some thinner blades from 15n20 or AEBL with a differential temper for toughness and make them as cost effective as possible. If I make them with a 180 grit rough bevel finish and no handle I could probably offer them in the $100 range. I have a design for a " true grass machete" I think could be good.
