Thanks for this thread. I hope it is not too necro for this post.
I recently bought a Martindale Golok, mostly for its looks, and for an attractive sale price. It sure is cute, but it doesn’t cut much, even with some file work to put an edge on the existing grind. I like the way it feels, but the grind is more obtuse than my Condor Golok, as well as just about every other machete I own. I have no experience in reprofiling a blade, but it has to be thinner, and I think the process will also convex it.
