Picked this one up today. Solid 'white metal'. Was quite tarnished and oxidised.
Nickel, white brass or low grade silver?
It marks very easily so is quite soft.
Quality seems good, it feels absolutely amazing in hand. Like a real fighter, great grip, comfortable and a good range of movement.
Can anyone add any information? Age, area, material?
I've seen plenty of brass and steel but never solid 'silver' metal.
