is it a full tang machete?
Full tang would mean you have two seperate handle slabs, one on each side, and can see the knife sandwiched between them at the handle.
Post a picture. I might be willing to fix it if you pay for the supplies and shipping.
All I see is blue ?'s
FWIW I was thinking of ordering this, or something very similar to craft them out of...
Micarta - Sheet - Canvas - Black - (3 x 12 x .3125)
But I have no idea on how to best fasten them together (or even shape the micarta but I will youtube that...)
