But since you asked

...
My "best custom tactical" folder is Tom Mayo's TNT.
It is my "holy grail" of folders for several reasons. I want a folder that will stand up to whatever task I put it to. I like the fact that the materials used are minimal, yet some of the best available.
I have owned other handmades and customs, yet I would not think of putting to task most of these as I have my TNT's.
I do not hesitate to use my TNT's for everything from cutting hoses that spring a pinhole leak under the hood of my 4 runner, to cutting up chicken or fish, or breaking bones in said food items in the kitchen. I have even used my TNT to scrape burned biscuits off of a baking pan, scraping tiny bits of the tray off in the process
The TNT is a marvel of skill, beauty, and craftsmanship.
After I get it all "gunked up" under the hood of my 4 runner, bloody and nasty in the field or the kitchen, or gritty and caked with Mississippi "Delta Gumbo" mud cutting vines and the like from my boots when I take my sons snake hunting, it is a simple matter to wash and clean my TNT with soap and water

. I never dry them off, and honestly don't remember the last time I thought to lube them. They are the smoothest folders I have ever had in my hand.
Don't even get me started about their superior cutting ability compared to other folders I've owned in the same price range

.
As far as fixed, I have several fav's there.
Well, I gotta go to work...
