That website is for POCKET KNIFE COLLECTORS.
CASE is really popular and for me it's the SWING GUARDS that I like.
GOOGLE "JA HENKLES swing guard 1930's" piece wow ! I missed out on a near NEW UNSED, UNSHARPENED one that when for about $400.00.
Now that's a goodie.
hahahah.
Swing Guard Knives are :-
"Knives That the Fella with the Switchblade Knife Should of Had"
You want a good blade go to "THAI Knives" they make UNBELIEVABLE PIECES BLOODY UNREAL...............
I purchased a few recvently and I am STUNNED how really god they are.
Also some with DAMASCUS BLADED folded steel about 220 times and crafted into something special.
Hope I was right and would love to know the little gems you have in the collection if you are a collector??
