what can you use?
so far, ive considered...
1.) cold blue (not very durable)
2.) read about something called "Tool black"? cant find it
3.) parkerizing. (but how do you keep the park from coating the edge?)
4.) some say that etching the blade with acid can help prevent rust and make it a grey color?
thanks
