We have made a modern weapons-grade pair of butterfly swords based on the original Ip Man BJD. The D-Guard is far stronger and wastes a bit less space than the original. The mouth of the quillon is wide enough for flipping to a reverse grip unless you have a big hand. The quillon flows more than the original, which had an elbow bend up. Instead of a blob of steel, the handle is a comfortable pair of black Micarta-type scales over an American-style full tang. We have also used professionally tempered weapons-grade blade steel.
