Its always nice to see people do things to their knives that you'd never do with yours - it gives you comfort knowing what it COULD do if you had to call on it in an emergecy, and I'd trust the DF w/ my life if it came down to it!
I love to see performance proven and to go beyond what the average person would do. ScrapYards are not primadonna's. Use, chop and enjoy...thats what its all about.
No Worries!
