Chris, thanks for the knife advice! I had no idea about the worthless sharpening stone (something I would definitely want to know about).<br><br>A couple more questions, if you don't mind: When you say 'bob' the top guard on the Ka-Bar, what do you mean? Also, when you talk about cutting the upper crossguard on the USAF- why would you want to do that?<br><br>Thanks<br><br>Peace and God Bless America<br><br>Chris
