Well first update, the spring-loaded blade plug! ;D
As some of you might know, most Graflex
blade plugs are held in place in the bunny ear/reflector holder ring thingy, so that when the plug is in, the bunny ears are a bit bent. (looking from the front)
And as I store all my sabers with blade plugs in (if they have) I really hated the bent bunny ears-effect.
So, what I came up with is
1" clear blade plug, with the graflex bulb-thingy epoxied on, with a spring, which pushes the plug so that it touches the ring but doesn't bend it.
