Some are 3/8,some are 1/2 ,making them different lengths,protoypes to be tested,with slight variences as well.
None of these have ever been fished as yet
.051 wire,should stand up fair to boat flipping,the origional white one did bend and one had to rebend every so often
The angle is correct,it has it built in,as works that way,if closer t the bait the willow will hit the hook or worse hangup,so was built with a sort of Stan Sloan drop bait angle.
Like any bait one gets one has to bend it or alter it after recieving a tad or fine tune to their own likes
Buy a buzzbait off the shelf so to speak bet you do tweak them a tad,most will bend the arm a hare or straighten the blade etc.
For a conventional buzzbait one of the best alterations one can do is to merely crimp the rivet down,makes more noise not turning with the blade
But buying a new one they arnt done that way looks used,and some mfg or fishermen dont know that.
Note angle of origional


Which is a 3/8,larger angle with larger hook and willow leaf take a tad more space to work .
Best explanation I can give,until you come here and toss one.
This is a subsurface bait designed to work under water,it does work on top as well,but designed for under.
