I know it is very hard to narrow it down to just one or two of your favorite knife manufactures but try! If necessary give a top 3. It can be a custom knife maker or a factory maker, any and all are welcome!
I would have to say...
1. ColdSteel- They are making some of the most high quality knives at an affordable price.
2. Ka-Bar- They too are also making awesomely affordable blades.
3. Its a Tie between Spyderco and SOG for me... A bit more expensive but totally worth every penny.
