I like it Tim
,
I thought most Dha blades were an 'interference' fit in the handle. Perhaps the tang was slightly 'over wrapped' before insertion, preventing a 'total' fit.
I love the idea of an old bike being broken up to use as parts....and using a wheel hub, a 'master' stroke. Nice blade, I wonder if the 'white' metal decoration are from old dry cell battery casings (if Zinc alloy).
Were small nails commonly used to fix the (shark/ray skin ?) wrapping on Dha ?
