Perhaps it's a silver Electrician that had been "colored" (paint?) and that has now worn off. I say this because a factory red knife would not have anodizing on the pins because the scales are anodized separately before assembly.
IIRC SAK Guy, you've a red alox pioneer (?) that's worn down similar to this one. Can you look at yours and see if around the pins shows anything? I may be wrong also. It does look like the red around the pins, but it could just be gunk or something too. Dunno.Thanks!
The last photo shows that the inside of the scale is silver, not red - I'd say it's a DIY paint job and not a factory red electrician.
Correct, there were no red Electricians from the factory as far as I know. That is red lacquer or paint there applied by somebody. Note the scales are not truly worn enough either.
