my name is Dan and I have an addiction......
LOL, seriously, I buy both knives to use and knives to display or admire...not that they can't or won't be used, just I tend to keep using the same knives over and over, and some have not made it into the rotation.
A few examples are a heavly used plumb bolo, modified by my Uncle when he was in the war, to a fine fighter. It will never see use again, unless me or mine get involved in combat.
I also have regular hunting knives for each of my different hunting tyoes, and also some "dress" hunting knives, that may or may not get used.
but most get sold if they do not get used in a year or two.
another way I get knives I will never use is in trade. I carry a sebenza for a folder, and when i get folders in trade I may carry them to try them out, but always end up getting rid of them and using the sebenza
