    Recently i bought these 2 Cold Steel Heavy Duty machetes as modding projects.
    One of them now looks a bit like a slender barong with a swedge (maybe this will be sharpened later on, don't know yet)
    The contoured & resurfaced polypropylene handle has a bit of a negative angle to the blade which so far seems to work well, but i haven't chopped wood with it yet.
    The convex edge measures around 30 degrees inclusive and is armhair shaving sharp.

    What remains of the second Heavy Duty machete after completely reshaping both the blade & the handle, pictured here below a slightly modified kukri machete.

    The idea was to combine an only 2.0 mm thick & lightweight machete blade with a modified kukri form which uses a more forward placed & pronounced belly as it's sweet spot, with an aggressively slicing forward curve as a follow-up.
    It's in the testing phase and i'm still working on it, but so far it has already proven to be very effective as well very easy on the wrist joints due to it's low weight.
    With a 45 degree angled hit at speed the blade will cleanly pass through a wrist size young birch tree/sapling, almost without feeling the impact.
    Thinner springy stuff that isn't immediately severed by a direct hit by the belly gets sliced by the forward curve, but most of the time the combination of a high tip speed with that curvy sweet spot is more than enough to do the job.
    The current convex edge is done on 400 grit wet & dry SiC paper on a rubber backing using WD oil as a lubricant, and measures ~30 degrees inclusive.
    The handle is contoured & fuzzy finished with the woodrasp.

    Playing around with crosshatching using a waterproof marker to check on the location & size of the sweet spot as well as the effectiveness of the slicing forward curve after a chopping session.

    Currently busy with giving the forward portion of the blade somewhat of a lenticular cross section to further improve upon pass-through cuts.
    So far i'm having a lot of fun for only very little money, :headfone:

    Current specs:

    Overall length: 51,2 cm
    Blade length: 37,5 cm
    Blade thickness: 2.0 mm
    Weight: 386,9 grams
    Steel type: 1055 carbon steel
    Hardness: ~56 HRC
    Handle material: polypropylene

    Still had these 2 pics on my wife's phone.
    Most green stuff around this size takes just one swipe at speed.
