PS, I wouldn't trade the Burt Foster for the Hinderer. JMO
That is one awesome blade. I wouldn't trade it.
Keep your knife.
Keep the Burt Foster. XM-18's are not hard to find as opposed to the Burt Foster.
Burt Foster is probably my favorite maker. Apparently don't know that much about him tho because I wasn't aware he made that type of knife. Which maybe is why it's so rare......I'd keep it.
That knife has pitting on the blade.
On the other hand, XMs are made in China now.
