I think i might get the KME system, and try it with broadheads too; i saw a thread on tradgang in which the lansky system is used for broadheads, i am only using 2-blade cut-on-contact's, so it seems like it would work. This means that i have the money to get the diamond system and use it on both knives and broadheads.
Also, what is the difference between diamond and stone? The only differences i can find are diamonds usually cut faster and only need water, not oil, and are more expensive.
Thanks, Carl
