I picked up this bayonet to go with my 1944 Lithgow. Looks like it has been redone. I was wondering if it looks right? It is kind of sharp, were they normally sharpened? Also can anyone tell me anything about the green frog on the other bayonet, it came on a bayonet I got for my Eddystone M1917? I have tried finding something similar online and couldn't find anything. Thanks in advance.
