Once Upon a Time, Long, Long ago, in a State of Mind Far, Far Away from what was considered normal, back before there was a Steel called INFI.
The Busse Combat Knife Company, made the toughest strongest knives available from the best tool steel to be found, A-2, and Jerry made the knives from Full thickness stock and the people found this to be good.
"Sharpened Pry bars" His detractors Sneered, "Sharpened Prybars, Cool" Most of the users Cheered.
And Thick Sold, so thick got made.
Then INFI came along and Thick got rare, so the value of thick went up.
Now you have your choice of thick or thin pretty commonly and reviews are mixed, but there is some thing for every one.
In Mid-size to small, I like Thin better as long as it is strong, (although I do like the way thick feels in my hand and how it looks)
In the Bigger knives, thick means you do not need the Battle Mistress, that the Steel Heart will do just fine, for the most part.
Buy Thick if you like it and move on to thin if you do not.
"There is no Try there is only Do"
I like Thin knives, I like thin women, I like Thick knives, I like Thick Women, I like thick Sandwiches and thick Bacon too.
So it appears that I an here for thick and thin.
